For centuries, a good, firm handshake has sealed many a deal.
Apparently, it has also spread many a germ.
Maybe, it's time to subject agreements to the fist.
According to scientific research that was recently published in the American Journal for Disease Control, a fist bump is 20 times more hygenic that a handshake and 10 times better than high-fives.
The reasoning is there is more contact area on the hand for germs to spread.
The most hygenic is the recently popular "bow-bow," the bumping of elbows.
