Week 3, Thing # 7: Technology: Too Much of a Good Thing?

In Sunday's New York Times (June 10, 2007) there was a small article in "The Week" section. A doctor in Spain, Julio Bonis, diagnosed a new medical condition after a patient complained of shoulder pain after rigorous bouts of playing tennis on his Wii.
The doctor called this condition "Wiitis". He prescribed ibuprofen and abstinence from the Wii. The patient experienced a full recovery.

I know that I played tennis on the Wii at the HCPL Technology Fair and had fun. However, can someone have too much fun with a video game?
