BBC - Programme 3: Nightwaves

Description

The Romans were very interested in it, the Vikings much less so and many think we're obsessed with it today. Cleanliness is central to religious ceremony, ideas about morality as well as health and the way we order our lives. Night Waves investigates what our relationship with cleanliness says about us in the twenty-first century and examines whether our attitudes are about to change again as water becomes a precious commodity.
