1.Amptated Arm = No Typing.
That's not exactly true. If you have one arm only, then you can still type. It's harder to play, but you can.
2.Amptated Leg = Wheel Chair most people in wheelchair dont play the computer.
Erm, I'm not sure. What will they do to pass time? Paint little statues? I'm sure plenty of those do play computer as well.
Heck, you play sitting on a chair, so, what's the difference?
3.Amptated Penis = Jewish Bris gone Horribly Wrong.
That doesn't stop you from playing computer
4.Amptated Head = Don't make me go there.
Well, a person with his head choped off might have some hard times playing computer, I agree...
