This is a delicate subject because one can view it as a call for those in their 20s to make the most of that time, which is a fine message, to something tantamount to ageism. While it's true that those in their 30s or older can be closed to new idea, that's not because they're "old", it's because they're people and some people are closed-minded. I find a lot of these complaints are more about the cultural and lifesty…
Yes, it's blatant ageism. As much as we hate to admit it, our minds and bodies start to decline almost as soon as we reach maturity. Not only does raw intelligence drop as we age, but some personality traits change. Of the Big Five, openness to new experiences takes the biggest hit.

Interesting links.
Perhaps I have some sort of Benjamin Button thing going on. I spent most of my "youth" being quite reserved. Up until my mid-20s I was primarily concerned with not screwing up what I believed to be precious, fragile success.
I've increasingly opened up as I've gotten older and at 33 feel decades "younger" than I did heading into my 20s for whatever that's worth.
I wonder what my chart would look like? Would I actually find myself rising in these regards relative to the average, only myself or not at all?
>Exercise, continuous learning, and a few drugs can help to slow the decline.
I could not agree more.
I credit frequent, intense exercise with at least a much benefit to my mind as my body and find boredom hard to fathom.
I'd put surrounding yourself and interacting with the right and likely ever-evolving set of people up there too. Complacency and conformity lead to mental atrophy.
