An interesting type of Energy

I was talking with Nick the other day. He and John are training for the Marine Corps Marathon and just ran the New York City Half-Marathon. We talked a little bit about what it feels like to run. He was saying how a crowd’s cheer (or even just turning a corner) can give an energy boost. Sometimes the right song and the right time can give that same effect, too. The whole concept is just really interesting to me. Real results and better performance can be derived from a small trigger.

It seems like the emotional state of our friends is contagious. We ourselves feel excited when good things happen to our friends. This is a great phenomenon, but it can work against us. When our friends experience unfortunate events, feelings of sadness are shared as well.
