There's a great article up on Yahoo! Reuters about the usage of video games by surgeons to help focus their concentration and skills for use within laproscopic surgical drills.  If anything, this further helps break down the idea that video games are a complete waste of time and hold no value outside of childhood enjoyment.

Quoting:

"A new study suggests that people preparing for surgery ask their doctor: "Have you played your video games today?"

Surgeons who warmed up by playing video games like "Super Monkey Ball" for 20 minutes immediately prior to performing surgical drills were faster and made fewer errors than those who did not, said Dr. James "Butch" Rosser, lead investigator on the study slated for release on Wednesday."
