I have heard the same thing bucky. I once read an article about a woman who decided to stop showering or bathing completely. She said the first number of weeks (I don't recall how many it was) were hard and she smelled really bad, but after that initial period her body regulated the smell and she and the people who were around her who were quoted in the article claimed she had an oder, but not an offensive one. They had pictures of her and you could not tell she had not bathed. She would wash her face I think, but she had not washed her hair and it looked silky smooth and clean. It was not tangled or matted or gross looking at all.
Personally I don't think I will be trying that anytime soon. The longest I have gone in my adult life has been 4 days and that was while camping at music festivals with thousands of other people who were in the same smelly situation as I was so no one noticed each others stink
