Wash your hands, wash your hands.

I noticed on google today that they were remembering Ignaz Semmelweis the hungarian physicist who is said to be the pioneer of anticeptic procedures. So having washed my hands lots of times and at much greater length than previously I thought a bubble blip might be in order. The NHS website tells us to wash our hands for around 20 seconds - the same length of time it takes to sing Happy Birthday twice apparently or the Archbishops suggest saying the Lord's Prayer which takes longer than the recommended 20 seconds- now there's a thought!
