Only 4% of people with Stephen Hawking's disease live for more than 10 years.

Stephen Hawking is an English theoretical physicist, cosmologist, author and Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge.

Hawking has achieved success with works of popular science in which he discusses his own theories and cosmology in general. Hawking has a motor neuron disease related to amyotrophic lateral sclerosis (ALS), a condition that has progressed over the years.

He is almost entirely paralyzed and communicates through a speech generating device. He married twice and has three children. In September 2013, he expressed support for the legalization of assisted suicide for the terminally ill.

Amyotrophic lateral sclerosis is an illness that only 4 % of the people that have it live for more than 10 years. However, Stephan Hawking has survived for over 50 years with it! Making him one of the strongest human beings around.
