Who gets the most dates in college, the athletes or the nerds?
Don't forget, when they say back in the day the life expectancy was 30, that did not mean people could get to be 90, it just meant people died from diseases a lot earlier but for a certain portion of the population but if you passed by those ages unscathed you could live to be 100 just like today, it was just that a lot smaller percentage got past 30.
They were innovative even 10,000 years ago, remember they were the ones who invented farming, quite an intellectual step and they for sure didn't have that many old folks.
Who gets the most dates might have something to do with the school too, like how much emphasis on athletics would there be at a uni like Princeton or MIT? You don't hear much about them getting into the top ten of football for instance. You hear about them in the boat races.
