That's why i mentioned breathing.
Long ago when humans HAD to learn in order to survive we were a lot more active.
Now we don't have to go out and catch out dinner, we merely go to the fridge.
When we had to run or be more active then we breathed harder and our brains recieved more oxygen.
Sitting at a computer for hours doesn't require much effort so our brains aren't recieving a lot of oxygen.
So breathing better and getting more active will lead to better performance mentally.
I'm no guru, just my perception of the state of play.Take is as you like.
