Good morning, @fpgargoyle. When you say, "It's past time for me to better educate myself about my conditions," you've hit upon our one real weapon in our fight to restrain PN, not ncessarily to defeat PN (that's likely impossible, at least at this time), but to retard its worsening. I'm 81. I was diagnosed when I was 78, going on 79. Not a day goes by when I don't try to learn a little something more about my cruel companion, PN. // Here's to you, @fpgargoyle! I wish you the very best. Cheers! ––Ray (@ray666)
