Think of all the times you shake someone's hand. Probably a lot, especially in the workplace. If you're worried about germs, you might want to skip shaking hands and settle for a high five or fist bump instead.

I once worked with someone who refused to shake hands with people. He was a complete germaphobe and simply wouldn't do it, which was a bit awkward for anyone who met him for the first time. Fist bump anyone?
