David Pierce was never someone who sat around watching life go by. He worked as a chef and had a catering business on the side. He sang in his church choir and did community theater, where he met his wife.
Then, in his mid-50s, doctors removed part of Pierce's foot, a complication of diabetes.
"My health just went, kind of really downhill. It really took a turn for the worse," says Pierce, sitting at his dining room table in his tidy home in Apalachin, N.Y. "I couldn't maintain even a part-time schedule."
