I usually go jump in the nearest river and clean my spear from the freshly killed buffalo that I ran down over the last 20 miles.
Nope. I usually shower once a day, in the mornings before work. Sometimes, if I feel mucky, I'll take another one before bed or before going out. Sometimes, if I'm just laying around the house on a day off, I'll skip.
I live on an island. I occasionally cleanse myself in the ocean, with lamb fat and lemon juice. Needless to say, I'm always pretty salty. A healthy amount of aloe plants makes your skin really comfortable.
