　　In most towns today, you can see teenagers standing before electronic machines with flashing lights, shooting at spaceships from other planets and dropping bombs on strange monsters(恶魔). The machines have names like Space Warrior, Dark Invader and so on. It used to be believed that damage was done only to these strange visitors from outer space, but now it seems that they are striking back.

　　Many teenagers like electronic games so much that they can't stop playing. They spend hours tightly holding the joy-stick controls and constantly pressing buttons marked with“fire.”They develop pairs on their fingers because of the constant pressure. They play and play so that the pains have no chance to heal properly. The rapid wrist movement required to guide the spaceship across the screen causes another problem, the muscles of the wrist and arm become so inflamed and swollen(充血红肿)that they press against the bones. This condition is what doctors now call“Space Worrior's Wrist”. Other strange aches and pains also tend to affect the elbows and shoulders.

　　Another even more alarming problem is shown by the case of a 17-year-old girl which was recently reported in the British Medical Journal. She had been playing various kinds of electronic games for more than two hours a day. Her father repaired games and machines and she could use the cassettes and systems in his workshop as often as she liked. One day, after playing a game called Dark Invador, she lost consciousness (晕倒) and fell to the floor.

　　Doctors who examined her found she was suffering from an unusual illness caused by lights flashing at a particular frequency.
