All the more reason to start earlier, so you have more lived experience on the job by your mental peak at 22. Instead your lived experience is playing Halo or something like that by that point. Or wasting time flipping burgers. Wish I could have dumped all the hours I did in restaurant work in highschool into research. The door was shut though until I got into undergrad even though I was a hard worker and could have picked it up then. A lot of parallels between food service and lab work, I learned after the fact.

Ah if you look at it from the perspective of doing research or other deep intellectual work by 22, I can see your point. Certainly if that is the peak of human mental capability (not something I can argue for or against but I'll take it as true) you ideally would pursue a focused education up to that point that allows you to dive deep into a challenging problem. IMO this is different from wisdom however, and in fact pursuing the variety of experiences and interactions with others that you need to build wisdom will distract from the focus on your research subject.
