I absolutely back what you say about Hawking but having a lot of money and a team of dedicated medical specialists at your disposal does help. Let's have a moment's thought for the non-public figure ALS sufferers who don't have those resources available nor a huge number of well-wishers across the world to keep up their spirits.
He showed ALS who's boss! He demonstrated that when you have a purpose and the will to live one can overcome their limitations.
He inspired me and countless of others.
R.I.P. Dr. Hawking.
