Tech-Gaming writes: "Although the 'sensation' is both sporadic and infrequent, most veteran gamers have experienced it during an intense play session. Typical symptoms include hand cramps- derived from inadvertently gripping the controller with vice-like force. Other signs may include eye strain, minor dizziness, and the inexplicable passage of large chunks of time. These indicators surface only when players are deeply immersed within a game, and when the diversion overwhelms us with uninhibited intensity. I like to call it the 'gamer's high.'"
