Welcome to the club, I reached that milestone a few years back. No big deal. I still feel as good and am in as good shape as I was 20 years ago. Riding keeps you young...the faster you go, the younger you get!
It is kind of freeing. I don't care what I look like when I go to the store, LOL. If I'm in the middle of a home or bike project, and I'm filthy and need to go to the hardware store to grab something I need for said project...I just go.
Good thing I don't golf, I'd be starting to wear mismatched plaid or something.
