Is There Science Behind That?

I think it's very important to not just make sure that there's science to back up these principles, but also to look at some of that primary research. I find one of the things that I find the most mystifying is the research done on stress and performance. Most of us don't need any more stress right now in order to have good performance. This research was done on mice around the turn of the century who were being electrocuted as they tried to exit a box through either a white door or black door.
