Giving a Brooklyn salute to all those parents who said videogames had no redeeming value, a study at Beth Israel Medical Center has shown that doctors who play videogames at least three hours a week make about 37 percent fewer mistakes in surgery, while performing 27 faster. Although anecdotal evidence (like Gulf War I’s ‘Nintendo Tank Pilots’) has indicated much the same for years, the study shows that surgeons who ‘warm up’ with videogames have a marked increase in coordination, agility, and accuracy when performing laparoscopic surgery using shotgun or chainsaw on zombie/alien patients.
