30 was a big one for me (unlike a lot of other posters, it seems) - I’d gone through most of my teens and 20s convinced I’d never make it that far. And then it happened, I was like “Woah!” and I threw a big party and …that was that. So, big at the time, but in retrospect, it were no thang. Birthdays are somewhat arbitrary, I’d rather mark my life by actual events - marriage, births, that kind of thing.
For what it’s worth, I felt older at 22 than I do now (more than twice that).
I turned 47 today. Physically and financially I’m in better shape now compared to when I was 30. The only thing that’s gone downhill is my eyesight. I need to take off my glasses to read anything. So don’t sweat it… you’ll likely have lots of good years ahead of you.
All I remember as to turning 30 was that Jerry Rubin died about the time I became untrustworthy. A drinking binge obscured my 40th birthday, but when my head cleared I felt the same way I had at 39.
I’m almost 50 and except for not being able to hear worth a damn and having musical ear syndrome (or jukebox-in-my-head syndrome) I feel a lot better and am doing a lot more than I did at 30. No rocking chair fuddy-duddy crap for me, I’m not going gracefully.
Interesting - me too. 30, 40, 50 were no big deal, but at 20 I realized I was halfway to 40, and I equated that to halfway to dead!
Oh, I hated it!
Guess what was easier?
Because the next one is 50 
Turning thirty was a bit odd. I had moved to a new city, broken up with a boyfriend, and had just got my very first all -by-myself apartment. (Turns out it was my last, a year later I moved across the country for my eventual ex husband, and since then have always lived with my child at minimum)
i had a friend in that city and we went out the night before my birthday… Since she and I both looked young, she joked “you are going to get carded if you are with me.” I joked, said I am an old lady, if I get carded I will kiss the bouncer, like a cougar!
I was carded by the bouncer (in a province where 18 was the drinking age). I went through with it. Never got carded again!
Moral of the story…don’t kiss the bouncer. It ages you.
Because I was born on the 13th, my ‘milestone’ birthdays have always been when it falls on a Friday – so I do’nt think any of the traditional birthdays have really meant much to me. Except actually when I turned 13; I was worried that suddenly I’ve have to be an adult and couldn’t play or do kid stuff anymore.
Shouldn’t that be Oh Fuck Thirty? An unconscionable hour to be out of bed.
My Thirties have rocked. Your twenties are for getting all the stupid crap out of the way so you can really enjoy yourself.
