Here, we look at a study reviewing data from the Darwin Awards, which concludes that - scientifically - men are idiots.
The Darwin Awards is an annual hall of fame commemorating those considered to have died in exceptionally stupid ways.
Wendy Northcutt, author of the Darwin Awards' website, describes the awards' rationale:
"In the spirit of Charles Darwin, the Darwin Awards commemorate individuals who protect our gene pool by making the ultimate sacrifice of their own lives. Darwin Award winners eliminate themselves in an extraordinarily idiotic manner, thereby improving our species' chances of long-term survival."
Although many of the early entrants in the Darwin Awards - collected during the web's relative infancy in 1993 - turned out to be hoaxes or urban legends, verified-as-real winners include:
James Burns of Michigan, who died while attempting to repair his truck from underneath while it was still in motion
Polish farmer Krystof Azninski, who won a "contest of masculinity," trumping his friends - who had stripped naked and were hitting each other over the head with frozen turnips - by cutting off his own head with a chainsaw
A terrorist who posted a letter bomb with insufficient postage and, upon its return, unthinkingly opened his own letter.
