We unconsciously touch our mouths, noses, and eyes many, many times each day. These mucous membranes are welcome mats for cold and flu viruses, which are readily transferred from unclean hands.

While it may seem amusing at first, this is really a very serious issue. The more people do their part to control the spread of infections, the less we have to use antibiotics, which lose their potency over time as bacteria develop resistance to them.

Although many Americans are beginning to recognize the importance of washing their hands, we still need to reach many others.

Our message is clear: One of the most effective tools in preventing the spread of infection is literally at our fingertips. Just 20 seconds of water, soap and rubbing can really cause an extremely wonderful intervention.

When Mr Ackroyd says that in the 18th century, stranglers bit off the noses of their victims, I feel that he probably knows what he is talking about. I just wish he hadn't told me.

I'd definitely say that when I'm alone with a girl, I'm doing the baby voices, all that stuff, rubbing noses, the whole thing.
