it helps you figure out when you've reached, or passed, your prime. when people start guessing your age correctly or saying you look older than you really are. you're over the hill :(
author=Link_2112 not really, altho i have stopped getting asked for id at a beer store
I always still get asked and I'm 27! Although, as of late, to counteract this, I've grown a mini-goatee for the summer to see if that would help, and it did. No more asking for my ID, now!
And, back on topic, my mom is almost sixty years old and she thinks that she's twenty-one. I guess age is nothing but a number (even if you do look like it on the outside).
