Martin Bayne entered an assisted living facility at 53 after he was diagnosed with young-onset Parkinson's disease. The disease affected his nerves so severely, it was impossible for him to take a shower and get dressed by himself.

"When I was in my 40s, I was physically fit and very active," Bayne tells Fresh Air's Terry Gross. "And to have to give all that up and stay in a wheelchair now and be helped by so many people to do the simplest of things — it takes a little getting used to."
