Of course, its made from waterproof material.
No. One is plenty, and it doesn't matter which wrist you use since it is all in your head.
Yes. Anyone can wear power balance wristbands.
Magnetic bands for balance
If you are right handed you should wear your power balance bracelet on your left nipple.
You can, but it's not the same effect. Power Balance bands are designed for as wristbands. I read that it doesn't matter. You don't even have to be directly in contact with it. If it is almost touching you it will still affect your body's balance. I'm a basketball player and accessories like this are prohibited, (They can get caught on the rim or other players fingers and so on) so I wear it under my socks around my ankle.
i am not for sure about the power balance but you may not wear a regular braclet
Yes, it will not break

If you are right handed, then wear on your left, or vice versa. But it doesn't really matter.
Chacos are okay to wear in the shower they dry very fast
