There could be more harmful bacteria on a computer keyboards than on toilet seats. British microbiologists James Francis took swabs from 33 keyboards and compared them with those from a toilet seat and toilet handle. The keyboards tested positive for a host of germs and bugs that could cause serious health problems like stomach flu and skin infections. One of the keyboards had bacteria 150 times more than the recommended limit, making it five times filthier than a toilet seat. Dropped food crumbs and poor hygiene were the main culprits.

The part of the brain associated with reward and addiction is more activated in males than in females when both genders play a game whose object is to acquire more territory. Researchers at Stanford made 22 undergraduates, half of them men and half women, play a video game that dealt with territoriality. The game involved gaining space by clicking on balls on the computer screen.
Although both genders clicked on the same number of balls, men quickly acquired more space than women, apparently because men were better at identifying which balls would give them the most space when clicked. According to the researchers, most computer games that males like to play involve territory and aggression, explaining why men are more likely to get hooked. The study could offer insights into what motivates human behavior.
