Hi,

This seems to have stumped the science teachers here where I work

Why can a cold sore transfer easily to other parts of your body (and other people too), but does not seem totransferfrom one lip to the other?

Love the show (http://www.thenakedscientists.com/HTML/podcasts/), listen to every one  (http://www.thenakedscientists.com/HTML/podcasts/)!
