For me, age 26, I'm already slower than I was when I was 18. I write better code though and can wade through harder abstractions, so on hard, novel material I'd likely win against my old self. Still, I really detest the "work" aspect of work which I don't wake up excited to do, so my plan that I'm on track for is to be "retired" by 32. Why slave until I'm 50? I've even considered depleting my savings earlier on to take a couple years off and then come back, delaying "retirement" by a few years but potentially making the "come back" slog much more pleasant. (I don't think I'll ever master the tricks other, often older, people seem to have about becoming excited to do even the mundane or just being able to plow through it regardless of 'motivation' or 'pleasantness'. My mother basically worked her whole adult life until she died, I don't understand how but sometimes wish such a mindset was more genetic.)
