As I read through the posts, two things strike me:

1. The 50+ bicyclers who have responded are generally pretty sophisticated bicycling folks, riding high quality machines, road bikes, other types of bikes, and are into "real" riding, not the typical stereotype that many have of "seniors" or "elderly" riders out for a Sunday ride.

2. The number of folks who also lift weights. As you gain more maturity in life, lifting weights is increasingly important to counter natural muscle loss and to fight against osteoporosis. Unfortunately, bicycling does not help in osteo prevention at all, as it actually promotes osteoporosis, so it is really important to do the resistive exercise activities. I happen to love doing them, so it is easy for me.

We now have 78 bicyclists on the forum who have self-identified themselves as 50+.

Good job, everyone.
