In most towns today,you can see teenagers standing over electronic machines with flashing lights,shooting at spaceships from other planets and dropping bombs on strange monsters .The machines have names like Space Warrior,Dark Invader and so on.
Many teenagers like electronic games so much that they can't stop playing.They spend hours tightly holding the joystick controls and constantly pressing but tons marked "fire".They develop pains on their fingers because of the constant pressure.They play and play that the pains have no chance to cure 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 that they press against the bones.This condition is what doctors now call "Space Warrior' s Wrist".
Other strange aches and pains are also likely 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.One day,after playing a game called Dark Inveager,she lost consciousness 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.
