I am closer to 50 and didn’t notice much decline yet, however to pre-empt it, I started journaling. I write down what I did per day, tech solutions, how I got to them, links to git repos, what I cooked with ingredients etc. It is fun to be able to say what I cooked Tuesday 3 September if someone asks ‘that Thai dish you made somewhere in December’ or ‘how did you fix that weird nodejs issue’? And it is inspiration for blog posts, tweets etc. For me it works wonders. Wish I started it when I was 17.
