Different people have different body chemistries, and varying degrees of funk. So while using a single towel per week works for me most of the time, i can fully understand and support those who really have to do so more often.

In the summer months over here, I regularly use more than 1 towel/week, because as I start to tan, work up a sweat more often, and am out and about in polluted city air, i can literally feel that my skin has more crud on it. It therefore just feels more comfortable to change towels more often in that kind of situation.

So given that, I guess climate has a lot to do with it too. If I were to live in any more of a warmer climate, my 1 twl/wk rule just wouldn't cut it.

To each his/her own i guess. Just don't bring the funk when I'm around.
