UK Channel 4 has been a pioneer of full frontal nakedness, and two new programmes have appeared.
One has the catchy title Naked, Alone and Racing to Get Home. It’s Naked And Afraid, set in Scotland but no parts fuzzed out at all.

The second is Naked Education, where people young and old, but mainly young, talk about what the naked body looks like.
