Sometimes it's better to be weird in just one way than several. So if you're going to be the guy who doesn't shower, it's best not to also be the guy who doesn't get haircuts, wears pants which are the wrong size, et cetera.

There have been so many articles about the troubles caused by bad gut bacteria, but hardly anything about how normal people can improve it.

This guy seems to have done both for skin bacteria.

It's worth noting that he washes hands (presumably after visiting the bathroom) and he bathes in order to remove dirt (as opposed to remove sweat)

So, if he (and this is speculation) washes hands after bowel movement, shouldn't he be washing that area regularly as well?

Also, horses do smell. Same for dogs. Try burying your nose in their fur, it's usually fairly smelly, unless the owner bathes the pet regularly.

This guy is brilliant! I want to do this.
