Okay, I get the health part but, considering many of my friends are very active in their 60s, 70s, 80s and, in a few cases, 90s in my other hobby, Square and Round dancing, I don't see age as that large of an issue.
That being said, I can't see you not attending a race or three next season so, who knows, you might even see me at a race next summer
I also disagree about you not being needed. That may be the case with the JAE but, when we look back at your contributions to the activity over the years(and I've seen your name come up in the various magazines plenty of times over the 35 years I've been in it), I figure you can still teach some of the new generation of "experts" a thing or two. I don't claim to be an expert and never will, especially since you've probably forgotten more than I'll ever learn
