Kebal Dari Sudut Scientific

Kulit Badak Sumbu tebal dan kalis api.

We see all manner of wondrous deeds about the seemingly invulnerability of the body to sharp objects or the extreme tolerance to pain, on the TV or in books, but...
have we ever seen someone demonstrate his survival after putting his body in the line of a firearm bullet? The former is just clever manipulation of science and ignorance on the viewers part.

Kebal? Mana ada? Even kereta kebal pun not really that kebal..

Pakai ler Kevlar vest kalau nak kebal. Heheheh...

Dari sudut saintifiknya, sesorang tu hanya bleh kebal kalau

1. Kulit dier keras giler dan bleh tahan tekanan yg sangat tinggi
2. Kulit dier elastik giler di mana kalau kena tusuk dgn pisau atau kena peluru, kulit dia akan mengurangkan Daya Impuls dgn memanjangkan masa pelanggaran.

Cuba bincangkan cara2 macam mana kulit seseorang tu bleh jadi kebal?

Mana ble jadik kebal...tipu jek superman tuh. Camera trick.

Kalau kebal secara saintifik aku tak leh nak explain.
Tapi macam mana kalau sesorang tu mempunyai force field shield???

Cuba buat ni..
Berdiri tegak, kaki agak2 jarakkan dengan selesa,
Depakan(depangkan) kedua belah tangan lurus ke sebelah(kiri kesebelah kiri dan kanan ke sebelah kanan)
Tapak tangan kanan menghala ke bawah dan tapak tangan kiri menghala ke atas.
Dongakkan kepala sedikit ke atas.
Diamkan diri selama 15 hingga 20 minit.
Anda akan rasakan satu tenaga mengalir melalui tangan anda.
Awas!! jangan amalkan selalu jika anda tidak mau tenaga dalaman anda mencederakan orang lain jika anda tidak boleh mengawalnya.
Anda akan merasakan satu getaran dalam diri anda.jika anda boleh mengawalnya dan memusatkan tenaga ini maka anda bolehlah menjadikan diri anda apa yang dikatakan kebal..

the only thing i know about kebal is

by mutation which is explained by genetics

ooh maybe i've watched too many episode of Greys Anatomy

tp aku pnah jmpe one of my classmates ni

die luka (did it on purpose sbb nk prove kt aku) tapi xrase sakit pn

n bile aku tanye apsal jd cmtu

die ckp genetics .. looks like sume org dlm family die ade problem cmtu jgak

hahaha .. aku caye jer kata2 die tu

so doktor2 kt sini leh explain x?

A child street performer who could stick knives through his arms and walk on hot coals without feeling any pain has led to a genetic discovery that promises a new generation of safer and stronger painkillers.

The Pakistani boy and six of his young relatives had mutations in a single gene that left them incapable of experiencing pain, even though their sense of touch is normal.

All have suffered severe injuries as a result of not feeling pain. Two have bitten off parts of their tongues, and the performer died on his 14th birthday after jumping from a roof.

Their cases, however, are of huge medical significance and could help millions of people who suffer intractable pain.

The discovery of a single gene that can switch painful stimuli on and off without affecting other body systems raises the prospect of a new class of analgesics with none of the side-effects of conventional painkilling drugs. Neuroscientists said that the findings could ultimately prove as important as the discovery of the receptor for morphine.

The gene, SCN9A, is responsible for making a protein called a voltage-gated sodium channel, which seems essential to pain perception.

In normal people, this protein is found in high concentrations at the end of pain-sensing neurons. When a painful stimulus is felt, the protein amplifies it and excites the neuron, sending an electrical signal to the brain so that pain is felt.

The mutation disrupts this process, making the sodium channel protein useless. Painful stimuli thus fail to reach the pain-sensing neurons, and no signal is sent to the brain.

The discovery, by a team led by Geoffrey Woods of the University of Cambridge, is particularly exciting because the abnormality appears to have no adverse effects in the children with the mutation, apart from the dangers that come with pain insensitivity.

This suggests that a drug that blocked the protein抯 activity could fight pain without the side effects that are produced by all the main analgesics available today.

Opioids such as morphine can cause respiratory problems, drowsiness and addiction, and can kill in overdose. Non-steroidal anti-inflammatories such as aspirin and ibuprofen can cause dangerous stomach bleeding, and COX-2 inhibitors such as Vioxx and Celebrex have been linked to heart damage.

John Wood, of University College, London, a member of the study team, said: 揟he work of Geoff Woods and his team has provided us with an exciting new target for painkilling drugs

camano mencederakan orang lain tu?
