Damn I thought this thread was going to be about a time machine so we could go back in time and Bomb the hell out of Kenya. Drat.
People used to only take baths weekly and women used to only wash their hair monthly. Then they used egg whites or beer to wash/rinse with. We think we have to bathe twice daily and that is foolish. Just a quick wash/rinse will get you clean. My wife fogs up the bath for 15-20 minutes and comes out looking like a cooked lobster. I am in and out in less than five and never have any body odor. Deodorant is not necessary to prevent BO, just a clean body.
Coconut oil is hypoallergenic, it is found in many skin products. It moisturizes and in and of itself it is antiviral and antifungal (kills yeast too).
addendum: A simple paste water and baking soda will work wonders for body odor as well. Years ago I tried an all natural deoderant. It was a giant hunk of rock salt. They repackaged it and sell it as Crystal Body Deoderant The stuff works. Apparently the salt just makes your body crevices so inhospitable to the bacteria that cause odors that they just die. Worked for me. YMMV. Oh, and after working hard and building up a sweat, just wash your pits, reapply and rock on. This contains no aluminum, no weird chemicals. nothing except mineral salts.
I've been using these "salt rocks" for over 20 years. One rock lasts me for about 2 years+. I have about 10 of them stored up. I highly recommend...I've haven't found a brand that doesn't work. They're all made out of the same junk as far as I can tell.
Hmm, read the last sentence.... "....it promotes healthy hair..." think about it.....is that really what you want?
