Sixty-nine years old, I'm a retired college professor and administrator living with my wife on a small farm, raising chickens and sheep. I'm a newspaper columnist and have a book out on my transition from being a college "suit" to a sweatshirt-and-denims country type. I'm also a Quaker recorded minister with a Master's in theology, plus a doctorate in English.My greatest concern is that Parkinson's will end my lecturing, pulpit work, and counseling of prisoners, and my ability to write. But I take my diagnosis as a message, and I'm determined to discern what I'm now meant to do.
