As children, my sister and I had a bath once a week, taking it in turns who went first.
Can’t remember when I started bathing more, we didn’t have a shower back then, but I seem to think when I was 17 or so, I bathed twice a week and washed in between.
Nowadays, I shower once a day, but don’t suppose I need to really.
Some people say they shower about three times a day, totally unnecessarily in my opinion.
My husband had a manual job, he certainly needed to bath or shower as he was often sweaty and grubby when he came home, but now he’s retired, not a problem but still showers daily.
I’m sure years ago we were no different to many others in our bathing habits, and I honestly cannot recall everyone smelling, but maybe I am looking at the past through rose coloured, or rose smelling, glasses!
