I stopped at 48. And I'm 6' even and not shrinking. Ever. That's my story and I'm sticking to it. I suggest taking a page from the Charlie Sheen book of self delusion. Get some good drugs, some hookers, and have a party the night before. Then, the next day you can dismiss it as the foolishness of youth.

(for the humor impaired...I'm a 60yr old grandfather who is making light of a situation...not actually advocating for drugs and hores...with apologies to good hores the world over)
