You know, all my life I hoped this would happen. Ever since childhood I expected it. I knew these creatures were alive somewhere, but I had no proof, scientific proof, and I had to keep it to myself, or my colleagues would have all laughed at me. -- Dr. Sampson, The Giant Behemoth
Here's an odd study to consider: using a 9 volt battery can make your skills at gaming better - as long as you can stand some small level voltage running through your head. According to an odd DARPA-funded study, running low-level electricity through the scalp might help the mind focus on tasks such as video games.
Obviously you do not want to try this sort of thing at home unless you are a complete moron.
