Why Do So Many People Smell?

If you live on the streets or are seriously ill or indeed, old and feeble you may have a slight excuse for not keeping clean - and even then, social services can usually help out.

Why do such a hefty proportion of clearly healthy people in my local Lidls smell? They aren't dressed badly; they aren't apparently poverty-stricken; they aren't anything other than in their pristine prime - and yet - they pong!
It ain't just Lidls, either.
5/6 bars of basic soap for a quid can last the best part of a year. Is it access to water they lack?
If you are wearing designer clothes, Levi-Strauss jeans, Nike trainers etc - you can surely afford a 59p deodorant spray! (Perhaps I shouldn't have suggested that - they'll just spray it on top of the dried sweat!)
What did John Wesley say? - "Cleanliness is next to godliness!" - Spot on.
