Well Im the exact opposite from most of you posters. I can;t stand to be dirty... I mean if I have to I will, but usually its every other day.
A few weeks ago on a Friday afternoon, not having had a bath or shower in several days, I was walking home and a friend came by in her car and picked me up - and complimented me on my smell. I think it's my diet; I eat lots of veggies and little meat. When the temp gets up to 38 though, I will have to shower pretty often.
