Do you use hand sanitizers (e.g. Purell) way more often than you should?

Only a couple times per week. Mainly after handling money and not convenient to get to a sink. I mistakenly believed what I was told five years ago that they were ineffective, but a good friend who is an epidemiologist says they are absolutely effective if hands are air-dried. You will now see them every fifteen feet in hospital ICU's.

I work in a hospital and use all day long!
