My experience is pretty much the same as yours. I feel sharper in some ways. I definitely work much smarter than I did in my 20s by magnitudes.

Although, mildly annoying, I find myself more frequently going to another room to fetch something and forgetting what the thing was.

Wiser, sure. More productive and efficient, sure. But raw cognitive power to learn wholly new ideas/languages, no way.

I dunno.. most of the spoken languages that I've learned I picked up in my 30s (bits of japanese, chinese, swedish, irish). I also took up piano at 38 and can play reasonably well, having never played an instrument before in my life.

I would agree with misterjangles about memory. My 6 year old daughter can beat me the odd time in various memory games. When I do beat her, I think it's probably because I'm relying on strategy as well as memorization. But is my memory getting weaker because I can use strategy instead, or is it just some kind of natural decline?

I wonder too, is your daughter more able to completely focus on the game?
