In our cool science news of the day, Time reports that the University of Cambridge published a study on the success rates of traders with high testosterone levels and those with lower testosterone levels. The researchers judged the testosterone levels traders received in the womb by measuring their ‘2D:4D’ ratio. The longer a man’s fourth finger is to his index finger, the more testosterone he was exposed to in the womb and the more responsive he is to the hormone as an adult. Not surprisingly, traders with higher testosterone levels were six times more profitable than those with lower testosterone levels.

Alarmed, I checked out my hand. Uh oh. Definitely not Steve McQueen hands here. I did a little more research at Wikipedia. It turns out that some scientists do use the ‘2D:4D’ ratio as a crude testosterone measurement. Women have equal ratio or 1+:1 ratio. My ratio? Equal.

You hear that? Crude. So maybe I have the testosterone level of a Sally. I can deal with that. I’ve dunked a basketball. Once. I’ll survive.

Stupid hands!

I’d love to hear what your 2D:4D ratio is. Let’s see who the machoest reader is!
