Quality of life is very meaningful in the context of lifespan. I suppose that's why the term 'health span' has become more popular. Why live longer if you or the people you love can't enjoy it?

I'm not even talking about that. I'd love to pound out code like I'm my late 30s the rest of my life.

In fact, it would probably be better than that. I'd be as quick as I was in my 20s but have the experience and knowledge of someone much older.

I definitely hit my coding peak somewhere in my late 30s. I don’t know how much slower I actually am, vs how much less I care. For one, I care to not write code that I’m not going to use. I spend way more time planning, talking about, and mulling over the thing I want to build, and I generally get it right the first time. Maybe part of the lesson of experience is not being in such a rush. Second, I’ve written so much code that I just don’t care as much about that activity as I used to. When I’m properly motivated to do something I still feel quick and energetic. I’m learning ASL with my girlfriend and she’s frustrated that I move faster than her, at some 13 years her senior. Maybe it will catch up to me eventually.

		These statements really ring home when i'm thinking about my 20s and coding. Back then, i'd dive right in, start coding, prove what works, figure it out as I go, then have to adapt the existing code to the figured out design. I was much more attached to that code and didn't want to lose it. Today, if I write code, I plan it out, have a good idea of how the pieces will work and then go implement it. And honestly, if the code gets thrown away, it's not the end of the world. Code is really a small portion of what engineers do...

		Chess players peak in their late 30s too.

Alas, perhaps those are inherent trade-offs, with experience also serving as baggage. After all, how would you code a lookup table that can grow indefinitely with no slowdown?

Fair point, and one of particular interest to me, age 76.

I find my short-term memory is in decline, magnitude depending on specific circumstances. This annoys me, and to a lesser degree, my wife as well. Really, where did I put that damned can opener?

But I also find my ability to find connections among phenomena in my technical field has markedly increased. In addition to my subjective perception, there's an outside measure, the annual rate of patent applications my employer files on my disclosures, and consequent cash bonuses. About a factor of 4x compared to when I was 60. As well (per my wife's telling), I'm better at remembering anniversaries and other significant dates in our lives and those of our family & friends. Anecdata, of course.

I'd say my age-related 'decline' has been uneven regarding details of cognition/memory, and at the moment provides me and my loved ones a better quality of life - certainly not what I expected decades earlier. It's complicated, and I'll be interested to see what more the posted research leads to.

		Thanks for your data points. They are quite encouraging. I was blessed with the ability to remember way more information that most of my peers. Now that I have lost some of that ability, I still retain quite a bit, with slower retrieval times usually. Over all, I really have no room to complain. ( although I still do). The skill I value the most though is finding those connections you speak of. I currently don't have a feel for how that has changed, but I think I am still good to go in that department.

That'd make a good sci-fi story. A world where science can keep anyone alive almost indefinitely but not their full faculties. So you get more and more "zombies" of barely alive senile elderly.

Also if I was a writer I'd call it "Congress" and have it start with senators. ;)
