Different people will have different comments on this post I think.
I think I am just as sharp as I ever was. I am in my early 50s. I do not however think I am as fast as I used to be. I can feel that. My understanding and abilities are solid as ever but I can see younger guys grokking things faster than me.
I also require way more sleep than I used to need.
The good thing though is that I have seen a LOT of things in my career in computers/programming/devops/engineering/math. So new things are just variations on things I have already seen over the years.
