Your brain doesn't finish developing until around that point, and it's the part that helps you control your thoughts and emotions (prefrontal cortex). There are no other advantages after 30, though, and the development been 25 and 30 isn't as vast as 18 to 25.
That said, I've been blessed with a middle aged 40 year old body since I was 12, so meh. (And really, I should have been given "most likely to do his taxes on time" title in the yearbook.)
For this I usually go with 27. Trade slightly more cortex development while only losing about 3% more of my collagen. So like one crowfoot and a forehead crease, but no more. Eyes are also stable enough for eye surgery but not going into retinal decline like in the 30s. Basically your late 20s rides off all your physical generation for a lot of different soft tissues being peak into ~25 but not having caused the damage that starts to build up and cause side effects in your 30s.
Anywhere between 28-32. Old enough that people take you mostly seriously but young enough that the world still feels like it’s set up with you specifically in mind.
Get a solid workout routine and make sure to stick with it. Whatever you want your goals to be, start now if you haven't yet. Don't put off taking care of your health.
If I can keep my current development I'd go for 25. Otherwise I'd prefer to stay my current age.
25 is a nice age but I wouldn't like to be an actual 25 year old in mind again.
I just turned 40 this year. I had the same thing when I turned 30 - I had wasted most of my 20s doing drugs and partying. I can honestly say that my 30s ended up being the best years of my life (so far)
I'd say probably 22-24. I'd prefer a little older for sure, but at age 25-26 a disease I didn't know I had got much much worse and has effectively robbed me of half my life. So a little younger for me.
I had a lot of growing to do before then, but at that point I felt like I had become a person I wanted to be. I actually had got back to school, so I was around a community of learners, and I felt like I was still on top of my job. I feel like I mulliganed my early 30s to the pandemic.
I think I would choose 30, but I'd like to do my 20s differently. Lifestyle creep is real. I notice my younger coworkers also make the mistake of spending way too freely. I'd also get married earlier. And take bigger risks earlier.
My vampire age was 45. Absolutely would keep that body forever, sex drive like a teenager but stronger, happier, more experience, physically I think that was my favorite but honestly feel great now too, and no chance of getting pregnant so maybe I'd keep this one.
I see people saying 25 and 30 but my life has definitely been an "it gets better" experience overall. 30s were the worst point so far.
40-50. (53 now) Around then you're old enough to have some gravitas, even if you don't try. People respect you automatically, which is weird.
You can still be in excellent shape and looking good. I kinda lucked out on that.
Bonus: If you have all your teeth and hair and are non-fat, the dating pool is smaller, but awesome. I was dating women I wouldn't have had a chance with when younger.
I am a lady, but had the same experience. Maybe a 5 as a 20 something, average in looks and the curvy short girls win the early rounds. Always had a few guys who thought I was the best thing they'd ever seen but not "majority attractive", understand? But just stayed in shape and waited, and, well, small don't fall so as a 50-something relatively much better looking. It was such a a surprise.
I was the thinest and fittest I've ever been in my life and I felt invincible, had tons of energy, could eat whatever I wanted and drink like a fish and still wake up early the next day without a hangover. God, I miss that body.
