Dinner is always the last thing I want before an improv show. Food slows me down mentally and physically, and I perform slightly better when I'm on edge with a little bit of hunger. Now there may be some proof that my hunger really does make me smarter, according to this New York Times article. When you're hungry, your stomach produces a hormone called Ghrelin, which attaches to your brain cells. When scientists inject mice with Ghrelin, they get through mazes faster and perform better on intelligence test. (What are intelligence tests for mice?) The article ends with the postulation that the fattening of American school kids is aiding to the decline of their test scores, and if they start eating less, they will begin to perform better. Of course, eating less is not going to happen. What's going to happen is they will have to take a Ghrelin pill for every 3 cheeseburgers they eat in the school cafeteria.
