“We have a tendency to be dismissive about games, but what we’re learning is that games in general are wonderfully powerful tools that can be applied in all sorts of serious contexts,” said Kevin Werbach, an associate professor at the Wharton School at the University of Pennsylvania, who teaches a course on how businesses can use games and recently wrote a book on the subject.

The adoption of games has found particular resonance in the workplace, where games are no longer just a way to goof off.

Employers like Reed Elsevier, the publishing company, are using a Web-based game service from a company called Keas that encourages workers to stay healthy by grouping themselves into teams of six and collecting points for achieving mental and physical fitness goals. Among the challenges Keas assigns: laughing randomly for 30 seconds. The members of winning teams at Reed each get $200 gift cards.

Laughing randomly for 30 seconds is good for health?

Memo to self: LAUGH MORE!

yes, yes it is.
