Katherine Ashenburg is the author of "The Dirt on Clean: An Unsanitized History" which explores our changing attitudes to washing. From the Romans who made bathing a complete social activity and spent many hours performing their ablutions, to the Middle Ages, when they believed water was the enemy and finally to modern times, when we are almost paranoid about our cleanliness. (Originally aired June 2009)
