Depends on who your friends and colleagues are. You might be surprised to find this attitude isn't universal or even common. No one I know would give the answer you suggest.

Pulled in my driveway after my ride today and saw a contractor marking trees for removal due to proximity to power lines. So I walked over to discuss what he planned take out. We talked about the trees a bit, said good day, and his final words were "stay healthy." He didn't see an old guy who looked foolish in spandex, he saw an old guy who was trying to stay fit. And I think that's what most people see.

There is of course a segment of the population that points and laughs. They often seem to align in other ways as well. I'm glad I don't know or associate with too many of that sort. Makes life a lot more pleasant.
