This is also my case. I spend all my day on a computer (and then the evening for fun) but a lot is thinking.

I always wanted to learn to touch type but never needed it so much that it would be worth to dedicate time for learning.

I do code a lot but I am a poor dev so I spend time thinking how to do things out looking at the docs (despite coding for 30 years).

It was even more obvious when doing my thesis (physics). 70% time thinking about code, 30 actually typing
