British doctors are claiming that the vibrations produced by some console controllers can lead to an injury called "vibration white finger" which is an industrial illness that is usually found in people that work with pneumatic drills or chainsaws for long periods of time.

"We believe that, with increasing numbers of children playing these devices, there should be consideration for statutory health warnings to advise users and parents. The potential for developing the hand-arm vibration syndrome should be considered, although more evidence of its occurrence in this context is required"

The boy was playing an offroad racing game with a rumble pack in his Playstation controller for up to seven hours a day. Some old saying about 'good things' and 'moderation' slips my mind.
