When it comes to a human being with an amazing mind, you have to admit that Stephen Hawking is right up there as being one of the greatest that has ever lived. Of course, his achievements take on even greater meaning when you remember that he has ALS.
But this is the one thing that is perhaps the most amazing thing in his life.
People that suffer from ALS do not generally live too long after they have received their diagnosis; it is just part of the disease. Step forward Stephen Hawking, because apart from being perhaps the most famous person alive today with the disease, he has also managed to live with it for over 50 years.
Now in his 70s, he was expected to die in his early twenties, so that is pretty remarkable.
