I'm not a germ nut, maybe even a little too much the opposite. But on occasion I shake hands with prominent people who, more often than not, are in town on a whirlwind tour, shaking hand, after hand, after hand. The first thing I do afterwards is head to my desk and get out the anti-bacterial hand cleaner.

From my end it's just one handshake but the other guy, one shake at a time, collects everyone's germs and takes them home to his family. Turns out, it's an occupational hazard for politicians, especially at campaign time.
