How Stephen Hawking, diagnosed with ALS decades ago, is still alive
The ALS Association says the average lifespan of someone diagnosed with the condition is between two and five years. Twenty percent make it past year five. From there, the number plummets. Less than 5 percent make it past two decades. And then there’s Hawking. He has passed that two-decade mark twice — first in 1983, then in 2003. It’s now 2015.
