There are several people in my office who have started doing this - with a twist. The guy from India in the cube next to me stopped bathing sometime last summer (2007). I got on an empty elevator today and was assaulted by the smell of unwashed bodies.

When I worked on the railway there was a guy who brought in "boil in a bag" fish and dropped it in the water boiler to cook it. Unfortunately this was the water we used to make tea. Fishy tea was not very popular .......
