Bernie Birnbaum! I just read throught this entire thread!! Jeez, that absolutely sucks about your wing. As I've gotten older I've discovered that I'm no longer made of flesh and bone . . . just Waterford fvcking crystal!! This constant chipping, dinging and occasionally shattering like my recent knee and wrist have kept me out of the gym, so I know what you're going through. It's hard to continue pressing on but if it makes you feel any better I've been through twelve 'scopes over the years . . . but rather than turn into a tub of ectoplasmic gelatin, I'm wheedling my way back into the gym.
I have to make myself the object of buffettes affections everywhere . . . or at least mitigate their wretching when they get a full frontal.
Hang in there mon!! Slow and steady gets the job done.
