Mandi pagi
kring.. kring.. alarm handphone berkumandang. 'Aishah terpisat-pisat sambil tangan menggagau mencari handphone utk mematikan alarm. sambil membuka mata yang berat, separuh je yang terbuka, ala-ala mata kucing garfield, 'aishah menelek, melihat jam. "oh sudah jam 4pg".. alarm dimatikan. 'Aishah kembali berbaringan. terasa berat untuk bangun, sambil mata terkebil-kebil merenung ke siling. entah ape yang difikirkan. kring..kring... tersentap 'Aishah. sudah 15 minit rupanya 'Aishah terkebil-kebil kerana bermula jam 4pg 'Aishah memang sengaja mengunci jap setiap 15minit. supaya dirinya akan bangun jgk. kalu x jam 4pg. mungkin 4.15pg, 4.30pg, 4.45pg dan sterusnya.
Akhirnya, 'Aishah bangun pada jam 4.15pg. kaifiat mandi pagi ni sudah dirasai dan dialami sendri oleh 'Aishah. cuma atas diri sendri je mampu istiqamah atau tidak dalam mandi jam 4pg ni. Aishah masih ingat pesanan nenek. kalu mau badan sihat, lambat tua, maka mandilah seawal jam 4 pg. kalu ade penyakit pun in shaa Allah boleh sembuh. sejak usia aku 22 aku sudah mula mandi seawal jam 4 pg tp tidaklah istiqamah. cuma bila "cuti" dan tak bersolat, mulalah aishah mula meliat nak bangun pagi sbb dh set xsolat subuh... huhu.. sedangkan, mandi pagi tu perlu xkira boleh solat atau sebaliknya. nenek pesan, semasa mandi niatkan supaya semua penyakit-penyakit yang ade di dlm badan keluar bersama seperti air yg mengalir pd badan. alhamdulillah, ape yang org tua bgtau sebagai petua itu byk kebenarannya. aku dh dpt rasakan kaifiat mandi pagi ni.
bila mandi pagi. hari itu akan bermula dengan penuh semangat. kulit akan berseri dan kelembapan kulit terjaga. minda akan cergas dan mudah untuk berfikir dan membuahkan perlbagai idea. badan terasa cergas. boleh menurunkan berat badan ke paras yang idol. kalu x menurunkan pun, akan me'maintankan berat badan, atleast xla naik. hikmah terbesar ialah dapat bertahajud dan beribadahlah bila bangun seawal jam 4 pg.
dapat baca al-quran sblm subuh, leh dpt syafaat. boleh buat bekpes, xyah beli atau makan kat luar. tidak terburu-buru kerana lewat. akan tenang dan emosi stabil dan ceria. jika rushing, ofcourse emosi mudah dan baran je kejenye.
jadi, hikmah bangun spertiga malam tu byk sgt. dpt beribadat. dapat menjaga kesihatan badan dan emosi. dapat menjaga aliran darah dgn mengurangkan makan diluar yg hukumnya makruh. nak atau x nak jer. sedangkan Allah dah jelaskan semua ini.
kring.. kring... alarm yg jam 4.30pg. alhamdulillah. ucap 'Aishah. harini dpt bgun awal. harapnya terus beristiqamah kerana Allah.
Wallahu'alam

Tips untuk mengurangkan keinginan makan bagi mereka yang obesiti:
a) Makan secara perlahan untuk setiap kunyahan
b) Guna pinggan atau mangkuk yang lebih kecil
c) Mulakan dengan kuantiti yang kecil semasa makan
d) Makan makanan yang lebih tinggi kandungan air dan minum air dahulu sebelum makan (sup sayur, buah-buahan, air kosong)
e) Makan di tempat tertentu sahaja (elakkan di depan tv @ semasa bekerja)
f) Makan pada masa yang tetap
g) Tidak meninggalkan sarapan kerana ini akan menyebabkan pengambilan makanan yang lebih banyak pada masa tengahari
h) Amalkan snek sihat seperti buah-buahan
i) Kurangkan kekerapan makan di luar dan hadkan duit yang dibawa ketika keluar
j) Atasi tekanan/masalah dengan sebaiknya.
Tentu ramai anda yang takut dan bimbang ditimpa pelbagai penyakit bukan? Jangan bimbang, kalau ada penyakit, pasti ada penawarnya. Senaman yang dirasakan sesuai untuk meningkatkan lagi aktiviti fizikal anda supaya tidak berlaku masalah kesihatan:
- Berjalan kaki dengan cepat, menaiki tangga, bersenam aerobik.
- Berlari, lari-lari anak (joging), berbasikal, berenang, atau merentas desa.
- Bersukan dengan bermain tenis, bola sepak, atau skuasy.
- Berjalan-jalan, berkebun.
- Melakukan kerja-kerja rumah, menari, dan aktiviti-aktiviti yang lain.
Anda tahu tidak kenapa kita perlu bersenam? Faedahnya banyak. Dengan bersenam, badan kita akan jadi sihat dan kuat. Kita juga akan jauh daripada pelbagai penyakit. Antara faedah lain daripada bersenam ialah:
- Senaman dapat meningkatkan kelembutan (kelenturan otot) dan membina kekuatan otot.
- Jantung bekerja lebih cekap ketika bersenam dan berehat.
- Meningkatkan kadar nadi dan mencegah pengerasan arteri, serta dapat menurunkan tekanan darah tinggi. Arteri yang keras merupakan penyebab utama berlakunya tekanan darah tinggi yang boleh membawa penyakit jantung dan angin ahmar (strok).
- Meningkatkan keupayaan badan mengawal paras glukosa darah.
- Membantu mengawal lipid darah yang tidak normal.
- Menguatkan tulang dan meningkatkan imbangan. Ini akan membantu mencegah atau memperlahankan proses osteoporosis (kereputan tulang) dan mengurangkan risiko daripada terjatuh yang boleh menyebabkan patah pinggang atau kecederaan yang lain.
Kanak-kanak yang kurus lebih aktif berbanding kanak-kanak yang gemuk.
Apakah yang dinamakan dengan obesiti?
Berdasarkan wikipedia, secara amnya, obesiti merupakan pengumpulan lemak berlebihan yang menimbun di dalam badan seseorang. Obesiti kini dianggap sebagai satu penyakit dan terjadi apabila tisu-tisu lemak menjadi keterlaluan. Lebih teruk lagi, obesiti boleh mengganggu dan mencederakan organ-organ badan dan seterusnya akan menyebabkan masalah kesihatan yang serius. Selain daripada mengehadkan kegiatan fizikal dan sosial, jangka hayat penghidapnya juga semakin pendek.
Siapakah yang tergolong dalam obesiti
- Mempunyai berat badan sekurang-kurangnya dua kali lebih berat berbanding ukuran ideal;
- Mempunyai berat badan sekurang-kurangnya 45 kilogram melebihi berat badan sepatutnya;
- Indeks Jisim Badan (BMI) melebihi 40 atau 35 (sila lihat di bawah untuk bagaimana mengira BMI);
- Mengalami beberapa penyakit seperti tekanan darah tinggi atau diabetes (kencing manis); dan
- Gagal mengekalkan berat badan yang sihat dalam jangka panjang sekalipun mengikut diet yang disarankan oleh pakar-pakar pemakanan
Apakah Indeks Jisim Badan?
Indeks Jisim Badan (BMI) (bahasa Inggeris: Body Mass Index) merupakan formula untuk menilai berat badan serta berkait rapat dengan ketinggian seseorang itu. BMI merupakan pengukuran tidak langsung komposisi badan kerana ia amat berkaitan dengan lemak yang terdapat dalam berat badan serta ketinggian seseorang individu itu.
| Indeks Jisim Badan | ||||||||
|---|---|---|---|---|---|---|---|---|
| Status | BMI | |||||||
| Kurus | Kurang 20.6 | |||||||
| Normal | 20.7 - 26.4 | |||||||
| Gemuk | 26.5 - 30.9 | |||||||
| Obesiti | 31.0 - 45.2 | |||||||
| Bahaya | Lebih 45.3 | |||||||
Jika anda ingin tahu berat badan serta ketinggian anda itu menepati ciri-ciri berat badan yang ideal atau tidak, anda boleh menggunakan pengiraan BMI seperti berikut:
Ukur berat badan anda dalam kilogram (kg) dan tinggi dalam meter (m):
| BMI = |
|
Setelah mendapat keputusan BMI, anda bolehlah melihat carta di sebelah kanan bagi menentukan sama ada anda tergolong dalam kategori gemuk atau terlalu kurus.
Kandungan lemak dalam makanan
Apa sahaja makanan yang kita makan, sebenarnya mengandungi banyak kalori daripada lemak. Di bawah ini, anda boleh mengikuti garis panduan diet Malaysia sebagai rancangan diet anda.
| Jenis makanan | Gram lemak setiap sajian | % kalori dari lemak |
|---|---|---|
| Makanan tinggi lemak | ||
| Hamburger saiz biasa | 11.8 | 39 |
| Hot dog | 14.5 | 54 |
| Kentang goreng | 20-25 keping (saiz biasa yang digoreng dengan minyak sayuran) | 12.247 |
| Keropok kentang - 1 aun | 10.1 | 61 |
| Mentega/marjerin - 1 sudu teh | 4 | 94 |
| Sos salad - 2 sudu makan | 11.1 | 85 |
| Kek keju | 16.3 | 57 |
| Makanan rendah lemak | ||
| Kacang hijau - direbus = cawan | 0.2 | 9 |
| Roti - 1 keping | 1.1 | 16 |
| Mil oat - 1 cawan | 2.4 | 15 |
| Buah epal - 1 biji | 0.5 | 6 |
| Ubi kentang - 1 biji dipanggang | 0.2 | 1 |
Jangan jadikan amalan, makan sambil menonton televisyen. Perbuatan ini boleh menyebabkan anda seronok sehingga tidak mahu berhenti makan.
Risiko kesihatan
Sekiranya berat badan anda bertambah, pelbagai keadaan serta masalah boleh berlaku, antaranya ialah:
- Penyakit kardioviskular (berkaitan dengan jantung)
- Strok (angin ahmar)
- Tekanan darah tinggi
- Batu hempedu

Eye disease: Keratoconjunctivitis sicca
Definition
Keratoconjunctivitis sicca (KCS), also called keratitis sicca,[1] sicca syndrome,[1] xerophthalmia,[1] dry eye syndrome (DES),[1] or simply dry eyes,[1] is an eye disease caused by decreased tear production or increased tear film evaporation commonly found in humans and some animals[2]. The phrase "keratoconjunctivitis sicca" is Latin, and its literal translation is "dryness of the cornea and conjunctiva".

wikipedia
Keratoconjunctivitis sicca (KCS), also called keratitis sicca,[1] sicca syndrome,[1] xerophthalmia,[1] dry eye syndrome (DES),[1] or simply dry eyes,[1] is an eye disease caused by decreased tear production or increased tear film evaporation commonly found in humans and some animals[2]. The phrase "keratoconjunctivitis sicca" is Latin, and its literal translation is "dryness of the cornea and conjunctiva".
Symptoms
Typical symptoms of keratoconjunctivitis are dryness, burning and a sandy-gritty eye irritation that gets worse as the day goes on. Symptoms may also be described as itchy, scratchy,stingyor tired eyes. Other symptoms are pain, redness, a pulling sensation, and pressure behind the eye. There may be a feeling that something,such as a speck of dirt, is in the eye. The resultant damage to the eye surface increases discomfort and sensitivity to bright light. Both eyes usually are affected.
There may also be a stringy discharge from the eyes. Although it may seem strange, dry eye can cause the eyes to water. This can happen because the eyes are irritated. One may experience excessive tearing in the same way as one would if something got into the eye. These reflex tears will not necessarily make the eyes feel better. This is because they are the watery type that are produced in response to injury, irritation, or emotion. They do not have the lubricating qualities necessary to prevent dry eye.
Because blinking coats the eye with tears, symptoms are worsened by activities in which the rate of blinking is reduced due to prolonged use of the eyes. These activities include prolonged reading, computer usage, driving, or watching television. Symptoms increase in windy, dusty or smoky (including cigarette smoke) areas, in dry environments, high altitudes including airplanes, on days with low humidity, and in areas where an air conditioner (especially in a car), fan,heater, or even a hair dryer is being used. Symptoms reduce during cool, rainy, or foggy weather and in humid places, such as in the shower.
Most people who have dry eyes experience mild irritation with no long-term effects. However, if the condition is left untreated or becomes severe, it can produce complications that can cause eye damage, resulting in impaired vision or (rarely) in the loss of vision.
Causes
Any abnormality of any one of the three layers of tears produces an unstable tear film, resulting in symptoms of keratitis sicca.Deficient tear production
Keratoconjunctivitis sicca is usually due to inadequate tear production. The aqueous tear layer is affected, resulting in aqueous tear deficiency (ATD) or lacrimal hyposecretion.The lacrimal gland does not produce sufficient tears to keep the entire conjunctiva and cornea covered by a complete layer. This usually occurs in people who are otherwise healthy. Increased age is associated with decreased tearing. This is the most common type found in postmenopausal women.
Causes include idiopathic, congenital alacrima, xerophthalmia, lacrimal gland ablation, and sensory denervation. In rare cases, it may be a symptom of collagen vascular diseases, including rheumatoid arthritis, Wegener's granulomatosis, and systemic lupus erythematosus. Sjögren's syndrome and autoimmune diseases associated with Sjögren's syndrome are also conditions associated with aqueous tear deficiency. Drugs such as isotretinoin, sedatives, diuretics,tricyclic antidepressants, antihypertensives, oral contraceptives, antihistamines, nasal decongestants,beta-blockers, phenothiazines, atropine, and pain relieving opiates such as morphine can cause or worsen this condition. Infiltration of the lacrimal glands by sarcoidosis or tumors, or postradiation fibrosis of the lacrimal glands can also cause this condition.
Abnormal tear composition
Keratoconjunctivitis sicca can also be caused by abnormal tear composition resulting in rapid evaporation[3] or premature destruction of the tears.[1] When caused by rapid evaporation, it is termed evaporative dry eyes.[3] In this, although the tear gland produces a sufficient amount of tears, the rate of evaporation of the tears is too rapid.[3] There is a loss of water from the tears that results in tears that are too "salty" or hypertonic. As a result, the entire conjunctiva and cornea cannot be kept covered with a complete layer of tears during certain activities or in certain environments.[3]
Additional causes
Aging is one of the most common causes of dry eyes.[5] This is because tear production decreases with age.[5] It may be caused by thermal or chemical burns, or (in epidemic cases) by adenoviruses. A number of studies have found that diabetics are at increased risk for the disease.[8][9]
About half of all people who wear contact lenses complain of dry eyes.[5] There are two potential connections between contact usage and dry eye. Traditionally, it was believed that soft contact lenses, which float on the tear film that covers the cornea, absorb the tears in the eyes.[5] However, it is also now known that contact usage damages corneal nerve sensitivity, which subsequently may lead to decreased lacrimal gland tear production and dry eye. The effect of contact on corneal nerve sensitivity is well established for hard contacts as well as soft and rigid gas permeable[10][11][12]. The connection between this loss in nerve sensitivity and tear production is the subject of current research [13].
Dry eyes also occurs or gets worse after LASIK and other refractive surgeries, in which the corneal nerves are cut during the creation of a corneal flap.[5] The corneal nerves stimulate tear secretion.[5] Dry eyes caused by these procedures usually resolves after several months.[6] Persons who are thinking about refractive surgery should consider this.[5]
An eye injury or other problem with the eyes or eyelids, such as bulging eyes or a drooping eyelid can cause keratoconjunctivitis sicca.[4] Disorders of the eyelid can impair the complex blinking motion required to spread tears.[6]
Abnormalities of the lipid tear layer caused by blepharitis and rosacea, and abnormalities of the mucin tear layer caused by vitamin A deficiency, trachoma, diphtheric keratoconjunctivitis, mucocutaneous disorders and certain topical medications are causes of keratoconjunctivitis sicca.[1]
Persons with keratoconjunctivitis sicca have elevated levels of tear nerve growth factor (NGF).[1] It is possible that this ocular surface NGF plays an important role in ocular surface inflammation associated with dry eyes.Treatment
A variety of approaches can be taken to treatment. These can be summarised as: avoidance of exacerbating factors, tear stimulation and supplementation, increasing tear retention, and eyelid cleansing and treatment of eye inflammation.[15]
General measures
Dry eyes can be exacerbated by smokey environments, dust and air conditioning and by our natural tendency to reduce our blink rate when concentrating. Purposefully blinking, especially during computer use and resting tired eyes are basic steps that can be taken to minimise discomfort.[15] Rubbing one's eyes can irritate them further, so should be avoided [6]. Conditions such as blepharitis can often co-exist[15] and paying particular attention to cleaning the eyelids morning and night with mild shampoos and warm compresses can improve both conditions.
Environmental control
Dry, drafty environments and those with smoke and dust should be avoided.[3] This includes avoiding hair dryers, heaters, air conditioners or fans, especially when these devices are directed toward the eyes.[6] Wearing glasses or directing gaze downward, for example, by lowering computer screens can be helpful to protect the eyes when aggravating environmental factors cannot be avoided [6]. Using a humidifier,[3][4] especially in the winter,[4] can help by adding moisture to the dry indoor air[6].[15].
Rehydration
For mild and moderate cases, supplemental lubrication is the most important part of treatment.[1]
Artificial tears
Application of artificial tears every few hours[3] can provide temporary relief.
Autologous serum eye drops
None of the commercially available artificial tear preparations include essential tear components such as epidermal growth factor, hepatocyte growth factor, fibronectin, neurotrophic growth factor, and vitamin A-all of which have been shown to play important roles in the maintenance of a healthy ocular surface epithelial milieu. Autologous serum eye drops contain these essential factors. However, there is some controversy regarding the efficacy of this treatment. At least one study (PubMed) has demonstrated that this modality is more effective than artificial tears in a randomized control study.
Additional options
Lubricating tear ointments can be used during the day, but they generally are used at bedtime due to poor vision after application.[1] They contain white petrolatum, mineral oil, and similar lubricants.[1] They serve as a lubricant and an emollient.[1] Application requires pulling down the eyelid and applying a small amount (0.25 in) inside.[1] Depending on the severity of the condition, it may be applied from every hour to just at bedtime.[1] It should not be used with contact lenses.[1] Specially designed glasses that form a moisture chamber around the eye may be used to create additional humidity.[6]
Medication
Inflammation occurring in response to tears film hypertonicity can be suppressed by mild topical steroids or with topical immunosuppressants such as ciclosporin.[16][17] Elevated levels of tear NGF can be decreased with 0.1% prednisolone.[1]
Fish consumption and omega-3 fatty acids
Consumption of dark fleshed fish containing dietary omega-3 fatty acids is associated with a decreased incidence of dry eyes syndrome in women.[18] This finding is consistent with postulated biological mechanisms.[18]. Early experimental work on omega-3 has shown promising results when used in a topical application [19] or given orally.[20].
Restasis
Topical cyclosporine A (tCSA) 0.05% ophthalmic emulsion is an immunosuppressant, marketed in the United States by Allergan under the trade name Restasis[1]. Approved as a prescription product by the U.S. Food and Drug Administration[5] in 2002, the drug decreases surface inflammation[6]. It is thought to work through inhibition[21] of transcription factors required for cytokine production and T-lymphocyte maturation.[22] In a trial involving 1200 people, Restasis increased tear production in 15% of people, compared to 5% with placebo[5].
Usually, 1 gtt (drop) of Restasis is instilled in each eye twice a day, 12 hours apart.[1] It should not be used while wearing contact lenses,[1] during eye infections [5] or in people with a history of herpes virus infections[6]. Side effects include burning sensation (common)[5], redness, discharge, watery eyes, eye pain, foreign body sensation, itching, stinging, and blurred vision.[1][5] Long term use of ciclosporin at high doses is associated with an increased risk of cancer[23][24].
Generic alternatives
Cheaper generic alternatives to Restasis are available in some countries. In India, it is marketed as Cyclomune by Sun Pharma.[25]
Conserving tears
There are methods that allow both natural and artificial tears to stay longer.[6]
Blocking tear drainage
In each eye, there are two puncta[26] — little openings that drain tears into the tear ducts[5]. There are methods to partially or completely close the tear ducts.[6] This blocks the flow of tears into the nose, and thus more tears are available to the eyes.[3]
Punctal plugs
Punctal plugs are inserted into the puncta to block tear drainage.[5] For people who have not found dry eye relief with drugs, punctal plugs may help.[5] They are reserved for people with moderate or severe dry eye when other medical treatment has not been adequate.[5]
Cauterization
If punctal plugs are effective, thermal[6] or electric[1] cauterization of puncti can be performed.
In thermal cauterization, a local anesthetic is used, and then a hot wire is applied.[6] This shrinks the drainage area tissues and causes scarring, which closes the tear duct.[6]
Customized contact lenses
Persons with severe dry eyes may benefit from the Boston Scleral Lens which is a customized contact lens.[6] Resting on the sclera, it creates a fluid filled layer over the cornea, thus preventing it from drying.[6]
Surgery
In severe cases of keratoconjunctivitis sicca, tarsorrhaphy may be performed where the eyelids are partially sewn together. This reduces the palpebral fissure (eyelid separation), ideally leading to a reduction in tear evaporation.wikipedia

kepentingan untuk menjaga frontal Lobe
Mengapa Frontal Lobe?
Frontal lobe atau otak depan, mengapa saya betul2 menekankan bahagian otak ini? Malah saya menganggap ianya adalah "pemandu" kita ke syurga. Frontal lobe seperti CPU pada komputer, seperti CEO sesuatu syarikat jadi jika rosak CPU atau lemah CEO bukankah keputusan dan tindakan2 yg diambil tidak betul dan tidak bijak. Jika kita punyai frontal lobe yg kuat dan boleh mengawalnya, kita akan lebih kenal diri kita sendiri, boleh mengawal diri untuk mengambil tindakan2 tertentu dan boleh mencorak masa depan yg lebih hebat.
Frontal lobe kurniaan Allah yg membezakan kita dengan haiwan, tempat terletaknya apa yg kita panggil akal. Semua bahagian lain pada manusia terdapat pada haiwan tetapi tiada yg amat ketara selain dari frontal lobe. Dari jumlah keseluruhan otak manusia, 30-40% adalah frontal lobe, tiada langsung pada reptilia dan jika ada pun pada haiwan yg lain, peratusnya kecil berbanding dgn manusia. Pada kucing hanya 3.5%, pada anjing 7%, pada keluarga monyet pula peratusnya dari 11 hingga 17%. Jadi jika manusia makin hari makin lemah frontal lobenya, bukankah manusia tersebut akan menyerupai haiwan atau lebih buruk dari itu? Haruan makan anak?
Saya menekankan yg solat merawat frontal lobe, mungkin ada yg berkata, aku tak sembahyang pun aku ok je, takde macam haiwan pun, aha.. jangan terpedaya, periksa diri ketika anda marah, ketika anda ditimpa musibah, ketika bersedih, ketika mendapat peluang2 untuk membolot kekayaan, ketika anda bernafsu. Ingatkan kembali adakah tindakan2 yg anda ambil pada ketika itu mengikut akal atau mengikut rasa/nafsu atau memori? Sebab itu ada beza bg yg solat dan tidak, dan amat berbeza lagi mereka yg khusyuk dan tidak.
Melalui kajian, ahli saintis mengira, pada setiap saat, otak kita memproses 400 billion bit maklumat jika dilihat dari perspektif komputer, tetapi apa yg kita sedar hanyalah 2 ribu bit sahaja, iaitu hanya 0.0000005% sahaja dari proses keseluruhan. Jadi perhatian kita kepada sesuatu itu pada masa2 tertentu amatlah sedikit, frontal lobe lah yg membolehkan kita mengawal kesedaran kita yg sedikit itu untuk menfokus pada sesuatu perkara.
Menurut Dr Joe Dispenza didlm bukunya Evolve Your Brain, beliau memilih "intent" atau niat sebagai fungsi utama frontal lobe. Mengawal apa niat kita untuk sesuatu agenda yg kita lakukan, bukahkah didlm Islam semua tindakan kita bergantung kepada niat. Berdasarkan niat2 tertentu ini kita akan mengambil tindakan2 yg tertentu, mengawal tingkah laku, merancang masa depan untuk mendapatkanya dan juga keinginan yg kuat dan berkekalan. Jika niat bersedekah mahukan keredhaan Allah kita akan membuatnya secara sulit, jika niat untuk membanggakan diri, manusia akan memanggil akhbar dan sebagainya. Semua tindakan kita secara keseluruhan pula bergantung pada apa niat kita hidup didunia ini, jika kita faham apa yg dibaca dalam doa iftitah "Innasolati wanusuki wamahyaya wamamati lillahirabbil alamin" maka kita akan mengambil jalan yg benar dan adil buat diri kita dan juga manusia yg lain, jika hidup ini untuk mengumpul harta, untuk kuasa, untuk nafsu maka tindakan begitu juga akan dipilih oleh frontal lobe.
Frontal lobe tempat untuk pemikiran yg kritikal dan juga mencipta idea2 baru, sama seperti tugas CEO syarikat, frontal lobe akan mengambil semua maklumat2 yg tersimpan dari bahagian otak yg lain, memerhatikan apa yg dilakukan oleh bahagian otak yg lain dan juga mengarahkan bahagian2 tersebut untuk melakukan apa yg perlu. Melalui "database" yg tersimpan dibahagian otak yg lain, ianya menjadi bahan mentah untuk memberi manusia cita2, keinginan dan inspirasi untuk mendapatkan sesuatu. Frontal lobe akan menimbang semua kemungkinan dan situasi, menganalisa keadaan semasa dan menjangkakan apa yg akan terjadi dari pilihan2 yg dibuat baik dari segi kesan kepada diri sendiri, masyarakat dan juga alam persekitaran. Selepas analisa yg mendalam ini barulah frontal lobe akan mengarah bahagian otak yg lain menjalankan apa yg diingini.
Frontal lobe juga membolehkan manusia belajar dari pengalaman dan memilih tindakan yg lebih bijak dimasa hadapan. Frontal lobe membolehkan manusia mempunyai cita2 yg hebat, mencuba sesuatu yg baru dan mendapatkan hidup yg lebih hebat dan tanpa batasan. Siapa diri kita, apa yg kita mahu sekarang dan masa depan dan kehidupan bagaimana yg kita hajati semuanya bergantung bagaimana kita menggunakan frontal lobe kita. Frontal lobe juga sebagai "alat" kita mencipta realiti kehidupan ini.
Frontal lobe membolehkan kita kekal fokus pada cita2 tertentu, berapa ramai manusia yg tetapkan banyak azam pada setiap tahun baru dan berapa banyak yg tercapai semuanya bergantung kepada frontal lobe. Tindakan2 manusia samada ikut akal atau ikut rasa ditentukan samada kuatnya frontal lobe atau tidak. Frontal lobe yg lemah, tindakan lebih kepada ikut memori terutama dari apa yg dilihat, didengar atau dialami walaupun ianya sesuatu yg salah.
Berikut adalah sifat2 yang ada pada manusia yg hebat frontal lobenya.
Boleh menumpukan perhatian pada sesuatu dalam jangkamasa yg lama
Berupaya menimbang semua kemungkian sebelum bertindak.
Boleh membuat keputusan dgn tepat dan cepat, tidak teragak2.
Jelas dalam semua perkara.
Ceria
Mahir dalam apa yg dipelajari.
Mudah menyesuaikan diri dgn perubahan.
Mampu belajar dari kesilapan dan tidak mengulanginya.
Sentiasa memikir peluang2 lain sebelum bertindak.
Punyai keyakinan diri yang tinggi.
Mampu bertindak mencapai keinginan atau cita2.
Seorang yg tinggi disiplinnya.
Mampu membina peluang yg lebih hebat berdasarkan pengalaman.
Tidak mudah terpengaruh dgn pengaruh2 luaran.
Boleh menumpukan perhatian hingga lupa pada persekitaran dan masa.
Minda yg tetap dan tidak melayang-layang.
Lebih proaktif dari reaktif.
Berpendirian tinggi.
Tidak pentingkan diri sendiri, lebih bersimpati.
Punyai impian, tujuan yg jelas dan hebat hingga tidak mampu digoyah keadaan luaran dan juga dari badan.
Banyak lagi sifat2 yg boleh di catatkan tetapi yg paling menarik adalah sifat yg akhir sekali, ingat bagaimana sahabat nabi yg diminta agar ditarik panah dikakinya hanya ketika beliau solat dan juga mereka yg tetap imannya ketika disiksa pihak Quraish. Bayangkan betapa hebat dan kuatnya frontal lobe mereka. Kita sekarang, nyamuk hinggap sahaja dah boleh rasa dan melayang fikiran dari solat.
Berikut pula sifat2 mereka yg lemah atau mati frontal lobenya.
Tidak terurus dan malas.
Tiada inspirasi, motivasi dan inisiatif untuk membetulkan sesuatu keadaan.
Suka pada benda yg sama, yang rutin dan boleh diagak.
Tidak keinginan untuk belajar.
Tidak boleh menumpukan perhatian.
Tidak boleh merancang untuk masa depan, tiada visi.
Cakap tak serupa bikin.
Tidak boleh menghabiskan apa yg dimulakan.
Reaktif.
Keras kepala dan tidak sukakan perubahan.
Selalu risau dan fikiran melayang2 memikirkan keburukan.
Tidak boleh mendengar dgn baik.
Bertindak melulu ikut rasa dan nafsu.
Selalu beremosi/moody, tidak ceria.
Pelupa.
Tidak boleh melihat/memikir kebarangkalian2 atau peluang2 lain.
Selalunya menjadi pengikut, tidak berpendirian.
Dari senarai2 tersebut sama2lah kita menyiasat diri kita sekuat mana frontal lobe kita ini, frontal lobe yg lemah membuatkan kita lebih mengambil keputusan ikut rasa dan ikut memori. Antara aktiviti yg melemahkan frontal lobe adalah menonton TV atau filem yg tidak membuatkan kita berfikir. Menurut Dr Daniel Amen melalui bukunya Change Your Brain, Change Your Life, TV dan video games adalah penyebab utama penyakit ADD (Attention Deficit Disorder) penyakit frontal lobe. Sebab itu jika dulu buang emak, buang saudara kerana kasih saya turutkan, sekarang buang emak, buang saudara, buang agama kerana kasih saya turutkan. Jika dulu tiada anak melayu yg hebat ber"lakon" aksi2 lucah, sekarang sudah banyak tersebar didlm internet. Semuanya kerana TV dan filem2 "sampah" yg di sumbat untuk melalaikan manusia dan hanya mengikut apa yg diperintah, tidak pernah terfikir mengapa TV amat dikawal? Kerana TV adalah alat hipnosis/pemukau manusia yg hebat, melalui TV juga manusia terpengaruh membeli sampah2 walaupun ianya tidak perlu untuk kehidupan.
Mengambil bahan2 toksid seperti dadah dan alkohol juga merosak frontal lobe, jangan terkejut bahawa merokok juga merosakkan bahagian tersebut. Rosaknya frontal lobe menyebabkan ketagihan terhadap benda2 tersebut tidak boleh dikawal oleh minda, tindakan ikut sedap rasa, bukan ikut akal. Tidak perlu ubat2an untuk berhenti merokok sebenarnya, cuma perlu kejutkan frontal lobe yg sudah lama terlena.
Bersolatlah dan berusaha untuk mencapai kekusyukan, amat beruntunglah mereka yg sudah mencapainya. Teramat benarlah bilal yg melaungkan azan mengajak manusia sembahyang dan menuju kejayaan, kejayaan dunia dan kejayaan akhirat. Negara boleh maju dari segi ekonomi dan teknologi, tetapi jika kejayaan akhirat dilupakan rosaklah akhlak manusia itu sendiri, jika tidak masakan Switzerland yg dianggap antara negara yg termaju didunia punyai kadar bunuh diri yg tinggi?
Bersolatlah dan sujud menghampirkan diri kepada Allah (Surah Al Alaq 96:16) ketika darah memenuhi frontal lobe. Frontal lobe, pemandu manusia ke syurga.

Frontal lobe seperti CPU pada komputer, seperti CEO sesuatu syarikat jadi jika rosak CPU atau lemah CEO bukankah keputusan dan tindakan2 yg diambil tidak betul dan tidak bijak. Jika kita punyai frontal lobe yg kuat dan boleh mengawalnya, kita akan lebih kenal diri kita sendiri, boleh mengawal diri untuk mengambil tindakan2 tertentu dan boleh mencorak masa depan yg lebih hebat.
Frontal lobe kurniaan Allah yg membezakan kita dengan haiwan, tempat terletaknya apa yg kita panggil akal. Semua bahagian lain pada manusia terdapat pada haiwan tetapi tiada yg amat ketara selain dari frontal lobe. Dari jumlah keseluruhan otak manusia, 30-40% adalah frontal lobe, tiada langsung pada reptilia dan jika ada pun pada haiwan yg lain, peratusnya kecil berbanding dgn manusia. Pada kucing hanya 3.5%, pada anjing 7%, pada keluarga monyet pula peratusnya dari 11 hingga 17%. Jadi jika manusia makin hari makin lemah frontal lobenya, bukankah manusia tersebut akan menyerupai haiwan atau lebih buruk dari itu? Haruan makan anak?
Saya menekankan yg solat merawat frontal lobe, mungkin ada yg berkata, aku tak sembahyang pun aku ok je, takde macam haiwan pun, aha.. jangan terpedaya, periksa diri ketika anda marah, ketika anda ditimpa musibah, ketika bersedih, ketika mendapat peluang2 untuk membolot kekayaan, ketika anda bernafsu. Ingatkan kembali adakah tindakan2 yg anda ambil pada ketika itu mengikut akal atau mengikut rasa/nafsu atau memori? Sebab itu ada beza bg yg solat dan tidak, dan amat berbeza lagi mereka yg khusyuk dan tidak.
Melalui kajian, ahli saintis mengira, pada setiap saat, otak kita memproses 400 billion bit maklumat jika dilihat dari perspektif komputer, tetapi apa yg kita sedar hanyalah 2 ribu bit sahaja, iaitu hanya 0.0000005% sahaja dari proses keseluruhan. Jadi perhatian kita kepada sesuatu itu pada masa2 tertentu amatlah sedikit, frontal lobe lah yg membolehkan kita mengawal kesedaran kita yg sedikit itu untuk menfokus pada sesuatu perkara.
Menurut Dr Joe Dispenza didlm bukunya Evolve Your Brain, beliau memilih "intent" atau niat sebagai fungsi utama frontal lobe. Mengawal apa niat kita untuk sesuatu agenda yg kita lakukan, bukahkah didlm Islam semua tindakan kita bergantung kepada niat. Berdasarkan niat2 tertentu ini kita akan mengambil tindakan2 yg tertentu, mengawal tingkah laku, merancang masa depan untuk mendapatkanya dan juga keinginan yg kuat dan berkekalan. Jika niat bersedekah mahukan keredhaan Allah kita akan membuatnya secara sulit, jika niat untuk membanggakan diri, manusia akan memanggil akhbar dan sebagainya. Semua tindakan kita secara keseluruhan pula bergantung pada apa niat kita hidup didunia ini, jika kita faham apa yg dibaca dalam doa iftitah "Innasolati wanusuki wamahyaya wamamati lillahirabbil alamin" maka kita akan mengambil jalan yg benar dan adil buat diri kita dan juga manusia yg lain, jika hidup ini untuk mengumpul harta, untuk kuasa, untuk nafsu maka tindakan begitu juga akan dipilih oleh frontal lobe.
Frontal lobe tempat untuk pemikiran yg kritikal dan juga mencipta idea2 baru, sama seperti tugas CEO syarikat, frontal lobe akan mengambil semua maklumat2 yg tersimpan dari bahagian otak yg lain, memerhatikan apa yg dilakukan oleh bahagian otak yg lain dan juga mengarahkan bahagian2 tersebut untuk melakukan apa yg perlu. Melalui "database" yg tersimpan dibahagian otak yg lain, ianya menjadi bahan mentah untuk memberi manusia cita2, keinginan dan inspirasi untuk mendapatkan sesuatu. Frontal lobe akan menimbang semua kemungkinan dan situasi, menganalisa keadaan semasa dan menjangkakan apa yg akan terjadi dari pilihan2 yg dibuat baik dari segi kesan kepada diri sendiri, masyarakat dan juga alam persekitaran. Selepas analisa yg mendalam ini barulah frontal lobe akan mengarah bahagian otak yg lain menjalankan apa yg diingini.
Frontal lobe juga membolehkan manusia belajar dari pengalaman dan memilih tindakan yg lebih bijak dimasa hadapan. Frontal lobe membolehkan manusia mempunyai cita2 yg hebat, mencuba sesuatu yg baru dan mendapatkan hidup yg lebih hebat dan tanpa batasan. Siapa diri kita, apa yg kita mahu sekarang dan masa depan dan kehidupan bagaimana yg kita hajati semuanya bergantung bagaimana kita menggunakan frontal lobe kita. Frontal lobe juga sebagai "alat" kita mencipta realiti kehidupan ini.
Frontal lobe membolehkan kita kekal fokus pada cita2 tertentu, berapa ramai manusia yg tetapkan banyak azam pada setiap tahun baru dan berapa banyak yg tercapai semuanya bergantung kepada frontal lobe. Tindakan2 manusia samada ikut akal atau ikut rasa ditentukan samada kuatnya frontal lobe atau tidak. Frontal lobe yg lemah, tindakan lebih kepada ikut memori terutama dari apa yg dilihat, didengar atau dialami walaupun ianya sesuatu yg salah.
Berikut adalah sifat2 yang ada pada manusia yg hebat frontal lobenya.
Boleh menumpukan perhatian pada sesuatu dalam jangkamasa yg lama
Berupaya menimbang semua kemungkian sebelum bertindak.
Boleh membuat keputusan dgn tepat dan cepat, tidak teragak2.
Jelas dalam semua perkara.
Ceria
Mahir dalam apa yg dipelajari.
Mudah menyesuaikan diri dgn perubahan.
Mampu belajar dari kesilapan dan tidak mengulanginya.
Sentiasa memikir peluang2 lain sebelum bertindak.
Punyai keyakinan diri yang tinggi.
Mampu bertindak mencapai keinginan atau cita2.
Seorang yg tinggi disiplinnya.
Mampu membina peluang yg lebih hebat berdasarkan pengalaman.
Tidak mudah terpengaruh dgn pengaruh2 luaran.
Boleh menumpukan perhatian hingga lupa pada persekitaran dan masa.
Minda yg tetap dan tidak melayang-layang.
Lebih proaktif dari reaktif.
Berpendirian tinggi.
Tidak pentingkan diri sendiri, lebih bersimpati.
Punyai impian, tujuan yg jelas dan hebat hingga tidak mampu digoyah keadaan luaran dan juga dari badan.
Banyak lagi sifat2 yg boleh di catatkan tetapi yg paling menarik adalah sifat yg akhir sekali, ingat bagaimana sahabat nabi yg diminta agar ditarik panah dikakinya hanya ketika beliau solat dan juga mereka yg tetap imannya ketika disiksa pihak Quraish. Bayangkan betapa hebat dan kuatnya frontal lobe mereka. Kita sekarang, nyamuk hinggap sahaja dah boleh rasa dan melayang fikiran dari solat.
Berikut pula sifat2 mereka yg lemah atau mati frontal lobenya.
Tidak terurus dan malas.
Tiada inspirasi, motivasi dan inisiatif untuk membetulkan sesuatu keadaan.
Suka pada benda yg sama, yang rutin dan boleh diagak.
Tidak keinginan untuk belajar.
Tidak boleh menumpukan perhatian.
Tidak boleh merancang untuk masa depan, tiada visi.
Cakap tak serupa bikin.
Tidak boleh menghabiskan apa yg dimulakan.
Reaktif.
Keras kepala dan tidak sukakan perubahan.
Selalu risau dan fikiran melayang2 memikirkan keburukan.
Tidak boleh mendengar dgn baik.
Bertindak melulu ikut rasa dan nafsu.
Selalu beremosi/moody, tidak ceria.
Pelupa.
Tidak boleh melihat/memikir kebarangkalian2 atau peluang2 lain.
Selalunya menjadi pengikut, tidak berpendirian.
Dari senarai2 tersebut sama2lah kita menyiasat diri kita sekuat mana frontal lobe kita ini, frontal lobe yg lemah membuatkan kita lebih mengambil keputusan ikut rasa dan ikut memori. Antara aktiviti yg melemahkan frontal lobe adalah menonton TV atau filem yg tidak membuatkan kita berfikir. Menurut Dr Daniel Amen melalui bukunya Change Your Brain, Change Your Life, TV dan video games adalah penyebab utama penyakit ADD (Attention Deficit Disorder) penyakit frontal lobe. Sebab itu jika dulu buang emak, buang saudara kerana kasih saya turutkan, sekarang buang emak, buang saudara, buang agama kerana kasih saya turutkan. Jika dulu tiada anak melayu yg hebat ber"lakon" aksi2 lucah, sekarang sudah banyak tersebar didlm internet. Semuanya kerana TV dan filem2 "sampah" yg di sumbat untuk melalaikan manusia dan hanya mengikut apa yg diperintah, tidak pernah terfikir mengapa TV amat dikawal? Kerana TV adalah alat hipnosis/pemukau manusia yg hebat, melalui TV juga manusia terpengaruh membeli sampah2 walaupun ianya tidak perlu untuk kehidupan.
Mengambil bahan2 toksid seperti dadah dan alkohol juga merosak frontal lobe, jangan terkejut bahawa merokok juga merosakkan bahagian tersebut. Rosaknya frontal lobe menyebabkan ketagihan terhadap benda2 tersebut tidak boleh dikawal oleh minda, tindakan ikut sedap rasa, bukan ikut akal. Tidak perlu ubat2an untuk berhenti merokok sebenarnya, cuma perlu kejutkan frontal lobe yg sudah lama terlena.
Bersolatlah dan berusaha untuk mencapai kekusyukan, amat beruntunglah mereka yg sudah mencapainya. Teramat benarlah bilal yg melaungkan azan mengajak manusia sembahyang dan menuju kejayaan, kejayaan dunia dan kejayaan akhirat. Negara boleh maju dari segi ekonomi dan teknologi, tetapi jika kejayaan akhirat dilupakan rosaklah akhlak manusia itu sendiri, jika tidak masakan Switzerland yg dianggap antara negara yg termaju didunia punyai kadar bunuh diri yg tinggi?
Bersolatlah dan sujud menghampirkan diri kepada Allah (Surah Al Alaq 96:16) ketika darah memenuhi frontal lobe. Frontal lobe, pemandu manusia ke syurga.

Different Parts of Our Body Age At Different Times
WE all accept that getting older is inevitable, and now leading clinicians have revealed the exact age when different body parts start to decline, most alarming being the brain and lungs.
French doctors have found that the quality of men's' sperm starts to deteriorate by 35, so that by the time a man is 45 a third of pregnancies end in miscarriage. Here, with the help of leading clinicians, Angela Epstein tells the Daily Mail the ages when different parts of the body start to lose their battle with time.
BRAIN - Starts aging at 20
As we get older, the number of nerve cells - or neurons - in the brain decrease. We start with around 100 billion, but in our 20s this number starts to decline. By 40, we could be losing up to 10,000 per day, affecting memory, co-ordination and brain function.
GUT - Starts aging at 55.
A healthy gut has a good balance between harmful and 'friendly' bacteria. But levels of friendly bacteria in the gut drop significantly after 55, particularly in the large intestine, says Tom MacDonald, professor of immunology at Barts And The London medical school. As a result, we suffer from poor digestion and an increased risk of gut disease. Constipatio n is more likely as we age, as the flow of digestive juices from the stomach, liver, pancreas and small intestine slows down.
BREASTS - Start aging at 35
BY their mid-30s, woman's breasts start losing tissue and fat, reducing size and fullness. Sagging starts properly at 40 and the aureole (the area surrounding the nipple) can shrink considerably.
BLADDER - Starts aging at 65
Loss of bladder control is more likely when you hit 65. Women are more vulnerable to bladder problems as, after the menopause, declining estrogen levels make tissues in the urethra - the tube through which urine passes - thinner and weaker, reducing bladder support. Bladder capacity in an older adult generally is about half that of a younger person - about two cups in a 30-year-old and one cup in a 70-year-old. ...
LUNGS - Start aging at 20
Lung capacity slowly starts to decrease from the age of 20. By the age of 40, some people are already experiencing breathlessness. This is partly because the muscles and the rib cage which control breathing stiffen up.
VOICE - Starts aging at 65
Our voices become quieter and hoarser with age. The soft tissues in the voice box (larynx) weaken, affecting the pitch, loudness and quality of the voice. A woman's voice may become huskier and lower in pitch, whereas a man's might become thinner and higher.
EYES - Start aging at 40
Glasses are the norm for many over-40s as failing eyesight kicks in - usually long-sightedness, affecting our ability to see objects up close.
HEART - Starts aging at 40
The heart pumps blood less effectively around the body as we get older. This is because blood vessels become less elastic, while arteries can harden or become blocked because of fatty deposits forming on the coronary arteries - caused by eating too much saturated fat. The blood supply to the heart is then reduced, resulting in painful angina. Men over 45 and women over 55 are at greater risk of a heart attack.
LIVER - Starts aging at 70
This is the only organ in the body which seems to defy the aging process.
KIDNEYS - Starts aging at 50
With kidneys, the number of filtering units (nephrons) that remove waste from the bloodstream starts to reduce in middle age.
PROSTATE - Starts aging at 50
The prostate often becomes enlarged with age, leading to problems such as increased need to urinate, says Professor Roger Kirby, director of the Prostate Centre in London . This is known as benign prostatic hyperplasia and affects half of men over 50, but rarely those under 40. It occurs when the prostate absorbs large amounts of the male sex hormone testosterone, which increases the growth of cells in the prostate. A normal prostate is the size of a walnut, but the condition can increase this to the size of a tangerine.
BONES - Start aging at 35
'Throughout our life, old bone is broken down by cells called osteoclasts and replaced by bone-building cells called osteoblasts - a process called bone turnover,' explains Robert Moots, professor of rheumatology at Aintree University Hospital in Liverpool . Children's bone growth is rapid - the skeleton takes just two years to renew
itself completely. In adults, this can take ten years. Until our mid-20s, bone density is still increasing. But at 35 bone loss begins as part of the natural ageing process.
TEETH - Start aging at 40
As we age, we produce less saliva, which washes away bacteria, so teeth and gums are more vulnerable to decay. Receding gums - when tissue is lost from gums around the teeth - is common in adults over 40.
MUSCLES - Start aging at 30
Muscle is constantly being built up and broken down, a process which is well balanced in young adults. However, by the time we're 30, breakdown is greater than buildup, explains Professor Robert Moots. Once adults reach 40, they start to lose between 0.5 and 2 per cent of their muscle each year. Regular exercise can help prevent this.
HEARING - Starts aging mid-50s
More than half of people over 60 lose hearing because of their age, according to the Royal National Institute for the Deaf.
SKIN - Starts aging mid-20s
The skin starts to age naturally in your mid-20s.
TASTE AND SMELL - Start aging at 60
We start out in life with about 10,000 taste buds scattered on the tongue. This number can halve later in life. After we turn 60, taste and smell gradually decline, partly as a result of the normal ageing process.
FERTILITY - Starts aging at 35
Female fertility begins to decline after 35, as the number and quality of eggs in the ovaries start to fall. The lining of the womb may become thinner, making it less likely for a fertilised egg to take, and also creating an environment hostile to sperm.
HAIR - Starts aging at 30
Male hair loss usually begins in the 30s. Hair is made in tiny pouches just under the skin's surface, known as follices. A hair normally grows from each follicle for about three years, is then shed, and a new hair grows. Most people will have some grey hair by the age of 35. When we are young, our hair is coloured by the pigments produced by cells in the hair follicle known as melanocytes.
