Yep. There are two more levels of maturity not generally recognized.
Something happens between 20 and 25, a 25 year old has a much higher maturity level than a 20 year old. I can't quite define it, but for the longest time I wouldn't bother date anyone younger than 25, even when I myself was only 20. (now my cut-off is closer to twice that...)
And the Founding Fathers recognized that a 35 year old had made the final plateau, and made it one of the few requirements for holding the office of the President. For that matter the number of first time arrests plummets after 35.
Agreed
Folks stop maturing at different ages
The more you continue to mature the better....I think anyhow
