At what point do birthdays go from being enjoyable ways to celebrate the acquirement of additional rights to dreary reminders of the fact that you haven't recorded a gold record, written a bestselling novel, climbed up a building using oversized suction-cups or figured our what an "IRA" is?

I think the answer is obvious. It's 22, right?

UPDATE: As WWB points out in the comments section below, at 35 Americans are given the right to run for the presidency. So is that birthday the benchmark? Well, at 55 senior discounts start to kick in. I guess the real question here should be at what point does the "dreary reminder" aspect begin to outweigh the additional benefits?
