I don't do much in terms of games, except for the fact that I go to a top school every day where they challenge me to no end with extension work, and that I hate using calculators, and would rather do as much as possible in my head.
I do eat a diet with a good amount of complex carbohydrates, fish and fish oils, as well as the correct vitamins. I take supplements every day.
Also, I've been managing to get 8hrs sleep/day, which is good.
And I never drink coffee. So much so that I've stopped liking the taste. I drink tea instead.
