...do you try to wash or Purell your hands afterwards?

The reason I ask is that I've noticed that a lot of people will shake your hand even if they are quite sick! So after I shake hands with someone, I try not to touch anything or anyone with that hand... until I can slip away and wash my hands with a little soap.

It's tough though because I shake hands with a lot of people every day! I'm probably overly paranoid about it, but I noticed that I rarely get sick these days while everyone around me has been dropped by colds and other ailments. So anecdotally at least, it's been paying off for me! I don't like washing my hands so many times a day though...

Do you wash/Purell after a handshake?
