You're only as old as you feel you are

This morning while I was out in service, this sister was telling me about this psychologist dude who has a book or something about a person's "eternal age." It's the age one feels they are, which can be quite different from their actual age. He said that most people stay a certain age in their head and a significant event in their life can play a part in what age that is. That being said, I turned 25(ish) again a couple of days ago. I refuse to go any higher than that - at least in this system. Maybe, if this system lasts long enough (though I really hope it doesn't) and I'm literally in my fifties, I might be ok with the term, "realy, really, really late twenties."
