Two comments on todays letters: 1)My brother-in-law, a teacher, not a parkie, lost his voice volume temporarily, and rigged up a microphone through a common tape-recorder to amplify his voice. If you like, I can get the specific details. 2)My experience has been that neurological pain is difficult to deal with. A friend had it with leukemia. (Incidentally, he was a chemist) He was able to keep working by using several helps. I can't remember all. One was the capsicum cream when it was first being developed. Another was to wear women's pantyhose. I can't imagine getting them on a parkie, though!! I hope Allen's friend of friend finds relief. Jan Kramar <[log in to unmask]>
