You guys waste far too much water. Back in the 1700's royalty would probably bathe four times a year at most.
I have bipolar and a common trait of bipolar is self conscious and awareness about one's body odor. We actually don't smell, but are hugely aware. That's why I shower so much. They aren't long showers so I don't mind.
I haven't showered in about a month now. I just run my head under the faucet and clean my face and hair.
