It matters less every age passed by? Do you mean the older you get? If so that's certainly not true. Like I said, for other people maybe but you don't do this for other people you do this for yourself. I know a lot of people who still hate being short that are 60. Why else would so many people save up for years and do this relatively late.
Matter of fact is, it's better to do it early but not because of your reasons but because you are more fit and have more life ahead of you. But there is no upper age limit really.
Yes, I can imagine myself being 180CM with LL on 23+ ....... my question is, and what?? I'm an adult already.
A friend and social life became less matter and matter when age passes by, most people married at age 25.
You have to take care of your wife and your future kid, being 2inch taller is too late, and barely doing anything by then.
Or you want to flex on your wife friend that you have 2inch taller?
on another side
Imagine you walk with your 6'0 gang in high school. No one wants to fk with you because most of your friends are at least 5'10+.
you get the attractive + hots (imagine how 16-17 attractive girls look likes) in your class and she is rich af.
Imagine how cool it is to borrow her car and pick up her at home and go to school every day.
After you go to a party multiple times, you're very charming because of your height and your personality.
now you got more connections, maybe someone at that party has a dad with a good connection that can bring you very far in business.
Of course, People on this forum are not getting my point and will be mocking me like '' HAHA man111 YoU LiFE IS ALl Parties!!''
This is just an example, there would be more many aspects of life that height can change your pathway in a better way, as a teenager
