Do you think that mental 'excercise' is more tiring than physical excercise?

Question

I used to play chess with my 12 year old son [he taught me] but with concentrating so hard, after 2 games I would fall asleep.

Answer 1

Yes, mental exercise is more tiring for me, too. When I'm physically exercising, it seems my whole body just wakes up!

Answer 2

I guess it depends on the mental exercise and the physical exercise. But mainly I would say physical exercise unless the mental game was Suduko - that game is very mentally challening.

Answer 3

yes.
