Boys will be boys, and so will a lot of middle-aged men.

I would say more. Many aged men will continue to stay boys. Is it bad? I do not think so. At least, it is much better than being an experienced tired grumbler. Ability to stay a boy is an intrinsic feature of Nature. If it is broken, boys are turned into creakers. Please do not say that you prefer creakers!
