I once asked my dad why he only took a bath once a week when he was a kid growing up on the farm. He replied, “Because they made me.”
ROTFLOL!
Now that is funny!
I cannot imagine living with one bath a week.
And I say this having lived without hot running for water now 9 years, and probably about 3 or 4 years total other times. I heat up water on the woodstove when it’s cold, and on the cooking stove (electric now, used to be propane) when it’s warm, pour it into buckets in the shower stall, and do a squat and pour. And when too tired (rarely), a sponge bath gets everything pretty clean when done carefully with a gallon or so of water.
When I lived in HI I just took cold showers a lot, you get used to it very fast in a hot climate. Refreshing, actually.
