Hear, hear.
I shower when I start to smell. That can be 2-3 times a week, but seldom more.
Today's "must shower 2-3 times a day" mentality is too far towards the "OCD clean" end of the spectrum (with Victorian era "bath once a week" at the other extreme).
It's actually not good for your skin to be continually washing it.
But then it's also not good for your hair to be continually shampooing it, either, but again modern society dictates you must shampoo your hair every day.
We've just gone from one extreme to the other.
Seriously, showering twice a day is waaaay over the top.
