πMental peak at 25 is a misconception
The common misconception is that man peaks mentally at 25 and then declines. Scientists used to think that way because the brain grows with the body/bones until 25 years and then there are no structural changes in the brain (therefore, they thought, the development stops). Since then, the scientists discovered neuroplasticity and other things (todo: which?) that shows that man continues to develop mentally (Kegan2016).
