We answered this question on the show...

Connie Orbach put this to Cheryl Trundle from Addenbrooke's hospital... 
Cheryl - When youíre talking about hand washing, the important things to know are when to do it, what sort of soap or what agent to use to wash your hands, and how you do it. And really, of those three, the most important is the good technique so itís how you do it. Any soap will be sufficient, any soap will work, but itís important you cover all the surface of your hands and you do it for the required length of time, and you need to do it before you touch a patient and after youíve touched a patient.
Connie - The required length of time? I always thought depended on how much of a rush I was in. Cheryl

Connie - The required length of time? I always thought depended on how much of a rush I was in. Cheryl:: Generally we say between ten and thirty seconds. About the time it takes you to sing Happy Birthday fairly slowly. Connie:: So far Dale, it seems your cleaning lady may have been telling porkiesÖ What about that gesture though?
Cheryl - Itís just so theyíre not tempted to touch anything. So they just hold them where they can see them so theyíre not touching anything dirty to contaminate them again. Then the water can wash down to the elbow so that the fingertips, which are the important bits, remain clean. It also lets the hands drain a bit so it doesnít take quite so long to dry them.
Connie - Well, there you go Dale. Thereís some method to the madness but donít ditch the soap just yet.Next week weíll be defying time with Troyís question...
Troy - If you were to live on Jupiter for fifty years and then return to Earth, what would the time difference be back on Earth due to Jupiterís increased gravity? Thank you.
