At age 58, going on 59, I'm feeling an alarming decline in physical (luckily not mental at this point) ability. Sure enough, men have relatively abrupt aging events at about 44 and 60. I hope that's what it is and it's not still coming and making things even more pathetic.

So I have, on average, another 7 years until I'm officially a typical old man? Great, just great.

But I can vouch for the earlier milestone. I grew up as a socially challenged geek with nobody to tell me that I'm just wired differently and it's not my fault, I didn't somehow not do my homework, that I'm not like the cool kids. Right around age 30 I had this epiphany... this is how I am! Instead of always looking for someone or something to teach me how I think I should be... just embrace what, in fact, I am. If I'm a geek, then just live my life best as a geek. The resulting increase in self-confidence did help socially. So just another prerogrammed "adulting" threshold? Maybe.
