Aye, but its one of them "meaningless" birthdays where there's nowt special about it apart from it meaning I've survived another orbit of the sun and I'm another year closer to a hole in the ground. Its not like 18, 21, 25 (give me my cheaper car insurance now damnit!) or even the 'ohs' (three-oh).
Saying that, birthday is on an aiki day. Its going to be painful!
