There's a lot of discussion of junk science in this thread. Instead, go here : [healthlibrary.epnet.com] and scroll down to the mention of Dabbs's study on the '94 World Cup and testosterone.
Now, knowing this, liken the Obama-McCain thing to a sporting event; those that win are exhilarated, and have a surge of testosterone. Those that lose take a testosterone-nosedive.
All that junk science make sense now? Good.
