2h. The rest of the time is spent thinking.

Does that imply you aren’t thinking whilst you work ;)

Staring into the screen doesn't solve any problems. Have to break it up somehow to actually think - notepad, conversations, walks, shower, lunch, and so on.

I know that is a joke, but: Yes, 2h of programming without conscious thought, total mental exhaustion afterwards.
