people's mental ability peak at 22?

Hi friend. My golden time is now!I think you have three option to mylot friends,past,present,futrue. some people regret to do or not to do something,thry lived in the past some people like dream the futrue,when I graduate from school,I will find a excellent job,and make much money,have a good wife and so on,but that's a dream so,I think my golden time is Now!I cherish this moment.

you only peak if you decide the next day to stop thinking and stop learning.. look at some of the best scientists and thinkers in history! they arn't 22 they are much older but are smart as a whip! Look at richard dawkins! he is well over 50 but still know so much and participates in every debate he can! thanks

This is one of the many things that varies with the individual. In most cases, I don't think our mental abilities are reduced with age unless there's a medical problem. I think it's more likely that our interests change, and so do we.

If I had to choose I'd say the golden time would 30.
