Surgeons who play video games shown to have better surgery skills

A study has found a direct link between skill at video gaming and skill at keyhole, or laparoscopic, surgery. Young surgeons who spent at least three hours a week playing video games in the past made 37% fewer errors, were 27% faster, and scored 42% better overall than surgeons who had never played a video game at all.

Interesting. If you read the full text describing the methodology, it looks like there are more variables than just playing video games. The surgeons who play video games tend to be quite a bit younger than those who don't. The non-game group isn't actually a control group. To make more of a case for video games being the determining factor, they would need to select surgeons who all fit into a fairly narrow band of age and training background, and then split them into the game/non-game groups. Also, the sample size should be a lot larger.
