A friend of mine (who's about fifty-eleven years old) saw my facebook status about riding yesterday and he complimented me but said he can't ride because he had knee replacement surgery (almost a year ago).

I want to smack him around verbally for making excuses, but then I started thinking, "Maybe one can't ride after a Knee replacement surgery, or how long is the usual recovery period from that type of operation before one can ride again?"

So let me know if I'm being insensitive, or if I can lay the smackdown on him!
