I have long suspected that poor behavior in men is correlated with their testosterone level, in kind of a bitchy man version of PMS. According to Tyler Cabot's piece in the August 2005 Esquire, maybe I'm onto something.
Irritability has been linked to "unhealthily low testosterone levels." Low testosterone may also be tied to depression. High testosterone levels, on the other hand, may make a fella more likely to smoke, drink, fight, and get hurt. Levels shoot up in the morning. Testosterone production gets a boost from a rigorous workout, in moderation; after an hour of exercise, levels start to drop. Sports fans whose teams win experience an increase in testosterone, whereas a losing team's partisans suffer a drop.
Help me with this theory. Do you know a man who pisses you off because he's extra irritable? Or who's cranky in the morning? Or who gets pissy around workout time? Who's totally unbearable when his team wins or when it loses? I can't figure out whether assholery would go along with low or high testosterone levels. I always figured it was high levels that produced the assholery. Mr. Tangerine gets extra-ornery when his team loses (low testosterone), but also tends to be grumpy early in the morning (high testosterone, but confounded by the factor of sleepiness). Let's do some science here, folks!
