The infamous physicist, who has been nearly fully paralyzed for decades, suffers from a degenerative disease called amyotrophic lateral sclerosis, also known as Lou Gehrigs disease. After diagnosis, life expectancy is a few years. About 10% live past ten years. So, how is it possible that Hawking has survived for decades, especially in a country that has a socialist rationed healthcare system that usually just manages terminally ill patients until they die. There is no point wasting money on them from the bureaucrats point of view. Indeed, Hawking was offered a nursing home in the 1980s, but his wife would not allow it. Unless he is an animatronic robot, or extremely lucky, he would have had to use capitalism to survive this long, which would be ironic, given his socialist predilections and defense of the horrid NHS.
