How to wash your hands - according to the experts

Rub palms together with fingers interlaced
Rub each palm over the back of the other hand with interlaced fingers
Rub between fingers on each hand
Rub backs of fingers (interlocked)
Rub around each thumb
Rub both palms with finger tips and then rinse with warm or cold water
Dry your hands well, ideally with a disposable towel
Use a disposable towel to turn off the tap"
After many many years of washing my hands now I find out I was doing it wrong! I always simply wet my hands, soaped them up, rubbed my hands together for a bit, and rinsed them off. Then dried them. I had no idea washing your hands was so complicated and had so many steps. I may have to take a class: "Hand Washing 101". Or read a book: "Hand Washing for Dummies".
