Derick Davies, 74, was diagnosed with the progressive neurological disorder in 2008 and experienced tremors for a number of years. But since teaching himself to play the piano, the disease progressed at a slower pace than doctors expected.
“I took it up because I need to help my coordination,” Davies says. “As you can see, I have got a tremor. When I play the piano, it gets better. This is with practice, of course!”
