When I am cutting, I keep a big chew toy in my desk drawer to gnaw on when I get hungry. I get great pumps in my jaws and extra aggression in the gym.
There are a few side effects. My wife gives me puzzled looks when I hump the postman's leg and howl at the moon every night. Also, when I go for a walk I get these irresistable urges to lift one leg and pee on all the trees I pass.
