> Playing piano really is a big mental challenge for me, as I try pieces just short of concert level. I believe that it helps keep me sharp. My grandmother lived to be 99, and she was sharp right up til the end. She was a violinist, first chair in a couple orchestras. She practiced every day well into her 90s, and also thought it kept her sharp. That, and "working her puzzles," which were word puzzles. She was the best I ever saw at cryptograms, and loved crosswords and even simple word searches. She was born in 1918, and she lived long enough to send me 20 years worth of emails. See you around, old timer.
