Hawking
When Hawking was 2 1 year old, Cambridge University announced that Hawking had severe amyotrophic lateral sclerosis. At that time, the hospital issued a notice saying that his condition was very serious. Hawking received many tests in the hospital, and various reports came from all over the world, as if Hawking could not pass this hurdle.
No matter what he went through, now he is working hard and miraculously alive. No matter who happens to this disease, what you see will never be hope. First, the patient's muscles are weak, like a pool of mud, and then slowly take away your ability to speak and swallow until you can't breathe.

The onset period of this disease is two to five years, half of people can live to three years, and 20% can live to five years. But it is rare for a patient like Hawking to persist for so many years, which is a medical miracle.
As for why Hawking can live so long, in fact, he doesn't know it himself. Even many doctors can't explain clearly. Hawking was different from many people from the beginning. This may explain why he miraculously lived for so many years. ALS usually occurs after the average human age is 55. When Hawking was 2 1 year-old, he got more opportunities to fight diseases and had stronger adaptability than people after 55 years old.

In addition, there are two possibilities for ALS to die. One is to make the patient unable to breathe and die of respiratory failure. On the other hand, it lost its swallowing ability and finally died of malnutrition and dehydration. If he is not affected by these two factors in the end, then he is more likely to survive. It can be seen that Hawking belongs to the third kind of people besides these two kinds of people.
