I minimize showering. Been doing that for years. I wash with
talc/cornstartch/whatever stuff. It grabs the dirt and excessive
oils off the skin just fine. Also hair as well. Doesn't matter
if it's wet or dry. If it gets the stale sweat and the dirt off,
it doesn't matter how. Why do I do it that way? I dunno. I did
it as an experiment once and found I liked it better than
soap/water/shampoo stuff. Some things need soap. Hands do for
example. Feet. But most of the body doesn't really get that
dirty.
