Believe it or not everyone has a smell and for some it can be quite strong without physical labor.

Not to mention weather can play a big factor as well.

Or due to allergies during allergy season.

There's many reasons to shower everyday.

And I'm not sure what you mean by making a difference between showering and washing. They're interchangeable terms given the context.

I cycle to and from work -- if I don't shower, that's not hugely kind to my colleagues!

I bet u smell bad :/
