I started to notice somewhat similar earlier in my life, around being 37 years old. I am 51 years old now. I have an advice: walk daily as much as you can, but no more than two hours, ruminating what is bothering and/or factinates you in your work. Thinking around the exercise time can be very helpful. And walking allows you to think while doing some exercise, which is even more benefitial. More than two hours of walking may result in more than 12 km of walk, which can be taxing. 5-6 km of walk is OK. Personally, I also do resistance training and intermittent fasting, but my primary tool is walking and was for a long time. Right now I am closing the bug that was introduced more than 10 years ago into the system I work with. I have more than four thousands of lines in changeset in more than four hundreds of files, in two unrelated repositories. So I think I am not all that bad at figuring things out. PS And sleep well! ;)
