That's one data point :)

I've stopped washing my body for a few years now. I do wash my hands regularly (with soap), I take a few saunas a week, and when I think I stink I take a shower with sodiumbicarb as a soap. I believe this is possible due to a fairly clean diet (eggs, dairy, union/garlic, meat, fish -- they make me stink and I no longer eat them).

My skin has never been better.
