1. You're getting old. Start writing everything down on paper.
2. Some people decline mentally faster then others, sometimes in their 40-50. Don't freak out, but do pay attention, ask others you know to pay attention to you.
3. Take it one layer at a time, and again, write everything down, best on paper.
Was just going to write this but with a minor modification.
It might not be getting old part but rather the boring nature of a mundane task, anyway writing things on pen and paper is best and works wonders to help iteratively understand problem and build a solution.
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.

And keep smiling when it is hard.
