According to an interesting new study, men who voted for Sen. John McCain in last year's presidential election experienced a drop in testosterone levels after Barack Obama was announced as the winner.
The testosterone levels of men who voted for Obama remained at the same levels throughout the evening.
The study's conclusion: "The present results suggest that male, but not female,
voters respond with testosterone changes to the outcome of presidential
elections as if they had personally fought to ascend a social dominance
hierarchy."
