Age is not as big of a factor as you might think when it comes to strength sports. In fact, I would say that most guys get better with age to a point. Bodybuilders don't seem to hang in there so well because of the steroids I suspect, but powerlifters and strongmen all seem to come into their own in their 30's and 40's... which is nice to know considering I'm starting into that realm

I figure I have a good 20+ years of competition left in me, should I so desire to do it.
Bodybuilders can't really say that.
