We were recently watching The Suitcase ep of Mad Men and Don says something like this to Peggy (though he says it about her twenties). I'd say at this point I am pretty much over birthdays. I've always felt old, but it's weird to start seeing physical evidence of aging. my complexion isn't as smooth as it once was, i have 2 or 3 wiry silver hairs, and my body does not bounce back physically the way it used to and i get injured more easily. i was watching some neighbor kids playing the other day and they were leaping off their front porch steps in flip flops. i resisted the urge to tell them that one day their knees will resign in protest. they'll find out soon enough for themselves.
