comment Math and mental fatigue
Thanks for the comments and answers! I have no idea this question would receive so many answers, I thought it would be closed within a day! Personally, I am trying out a combination of short naps and strength training exercise to increase my physical and mental stamina. Hopefully it will reduce the mental fatigue!
