That amped up feeling you get from watching your favorite team win a nailbiter also causes your hormonses to spike, according to research recently conducted in Europe.

Doctors took saliva samples from 58 test subjects during the 2010 FIFA World Cup final. That game, for those who do not remember, was won in overtime as Spain scored a goal in extra time to beat the Netherlands.

When the test was complete, researchers noticed that both testosterone and cortisol levels were elevated in the spectators compared to others who did not watch the match.
