Like a bunch of others, 30 never bothered me...25 did, because I couldn't think of it as "25", but rather, "1/4 of a century".

Individual years since then have ocdcasionally bothered me, but not because of any particular year or milestone, just because my life happened to suck right about then.

Lilith may be on the right track here, though...if you moon the rest of us, that may put you back in the right mood.
