All these yummy flavors

Why does dental floss need to be flavored? Do billy-goats and people with polyphagia choose it over string as the tastier snack?

For that matter, why does every hygiene product known to humanity need to be flavored? Shampoo that smells like mountain sunshine; honeysuckle bodywash; icy blast deodorant; hair stuff that smells like coconut; hand soap smelling of coffee and bananas; eucalyptus shaving cream -- the combination of it all gives the impression that the wearer has tumbled into the perfume kiosk at Macy's. It's a smell cacaphony.
