Think about this after the next time you shake hands with a stranger.

[Phinnaeus Gage]

The man you just shook hands with probably masterbated using the same hand within the past 72 hours. Also, on average, they'll less likely to wash their hands on a regular basis.

That said, consider going for the full frontal hug if you're a compulsive hand shaker.
