Earlier quoted context omitted.
I'm living in apartment and shower twice a week (at least in winter). Never understood obsession with daily shower as seen is American movies, no wonder Americans have extreme water consumption, I wonder how common is eczema and skin diseases over there compared to countries which shower less. EDIT: instead of downvoting rather prove me wrong, do you think Americans don't have extreme water consumption? US water cons…
If you do any physical work, you get sweaty, sweat means bacteria, means bad smell. Some of us don't like to stink, also don't like our beds to stink.
Fun fact- most Koreans don't have the same sweat gland that many others have that produce the type of sweet that the stinky bacteria feed on, and thus don't stink like Americans from sweating (they do have their own smell, from what I understand, but it isn't as pungent) and thus they don't usually use deodorant/antiperspirant. It is my understanding some other Asian groups don't stink or don't stink as much, as well, due to differences in the sweat produced.
