Come now,this is silly.
There are people in their 60s that are so physically fit they can win a fair fist fight against a 20 something year old who ever so rarely works on his/her muscles.
Why is there a presumption that intellectual capacity is any different? A person that trains their mind will do better than those that don't,that's obvious.but how many people reach anywhere near their intellectual maximum capacity?
My theory is that as people get older the items of life take up much more of their time than in their earlier years which steals their potential to maintain or exceed their earlier intellectual capacity. Those that manage to make time for a mental workout in latter years would likely feel as competent as when they were young if not more.
Just a theory based on observation.
- Waterluvian 8y agoI hear you. But consider this. So you're making a case that you can exercise muscles and cardiovascular system, so therefore you can exercise the brain. But what about other organs? Can you keep skin youthful through exercising it? What about hair? Eyes? I think it's equally as plausible that no, you can't exercise the brain just by using it well. (though I don't personally believe this)
- aeternus 8y agoThere is also clearly a peak and decline, even with exercise. The article does seem to cover this given the wide error bars for some of the cognitive tasks.
- jimmy1 8y ago> Can you keep skin youthful through exercising it No but you certainly can by avoiding excessive sunlight exposure and staying hydrated!
- badrabbit 8y agoIntellectual capacity increases when people study intellectually demanding subjects and decreases when neglected,this is similar to the muscular and cardiovascular systems and afaik undisputed.
