Some people like to shower every day or even twice a day but not because they are more dirty to start with, just because they actually care more about being clean!
I don’t feel the need to shower twice a day, and it’s not because I don’t care about being clean 
These threads always get a bit competitive cleanliness- if you don’t shower three times a day, wash your bed/clothes/towels every day then you’re minging and smell.
Fact is most people don’t smell and aren’t filthy if they shower every other day. I’m old enough that i didn’t have a house with a shower until I was 21. Baths aren’t as convenient and growing up it wasn’t unusual for adults to bath twice a week, children once, often in the adults bathwater as immersion tanks only held enough for one bath.
My mum had a twin tub and clothes were worn for two or three days as no tumble dryer, no large capacity machine.
What I find horrible these days is the people who’s clothes are very strongly fragranced with detergent/softener. I can’t bear the smell so strong and have to move away. I coach sports and need to touch kids to show them how do do things- some I can’t go near.
Same when I was buying a house recently- some were so heavily fragranced with candles, sticks, plug ins etc i had to leave.
We are all paranoid about smell- fuelled by the people selling us deodorant, laundry products, perfumes, candles, plug ins... i prefer the normal human smell.
Chemical perfumes do not smell nice!!!
