I'd like to lend my support to "old enough to realize that the real world sucks". By that measure, I reached adulthood two weeks short of my 25th birthday. That, of course, was when I was laid off for the first time, just after signing a year-long lease on a new apartment. That's probably just coincidence, though. I'm sure that many people realized the real world sucks earlier than I did.
