I used to work with this hyperactive skinny computer programmer who was always bounding about the office boing, boing, like Tigger crying "Feed the Code, Feed the Code!" Brain work makes you hungry. It certainly made him hungry anyway, and he was a genius. Smartest guy I ever met. Could play the linux command line like a piano, not kidding, it was incredible.
Anyway, I agree with the above ideas. I used to snack on Dulse seaweed for a while there.
