Maybe, but you just know Twitter OP smells like spoiled milk constantly and he uses this as a justification.

Yeah you'll dry out your hair if you shampoo that much. Then you'll have to condition it often to keep it good. Same deal with thorough soaping -> using lots of lotion.

I wonder how many people are actually scrubbing themselves raw everyday.

It's an individual thing, some people "stink" easily. from google:

research points to the ABCC11 gene as directly responsible for underarm odor. Oddly enough, this gene also determines whether people produce wet or dry earwax. Interestingly, those who tend to produce dry earwax also lack the necessary chemical needed to feed the bacteria that cause underarm odor.

East Asians have dry earwax.
