I'm the complete opposite, I'm an old man. I've been an old man for about 8 years now I'm almost 40. My friends either disagree with me or piss them off (if they're older than me) when I say, "I'm old".
At some point you'll be talking to someone a lot younger than you and realize that somehow they're still an adult and then immediately after they'll do something incredibly immature. Will make that top line will drop so fast.
The state of being old is a whole bunch of things that correlate with chronological age, but unless you know someone moving at relativistic speeds, chronological age is the only one we all move through at the same rate.
If you can hold on to the good bits of youth, like open-mindedness, and grow along dimensions like maturity, maybe youth doesn't need to be wasted on the young.
could you bother to share some tips, like the perfect brand to get the anti aging vaccines from, or that super duper bone density improvement kit. The brands i have been looking at at really expensive, the last one i tried was asking 127 quintillion, plus taxes. PLUS TAXES! those cheapskates
