You know you've seen them...
disturbing the flow of the aisles in the supermarket by reading the labels of every product they buy...
comparing 6 brands of canned tuna to find out which contains less mono or polyunsaturated diglycerides per serving on the odd chance that doing so will make them live longer... though any extra time they'd live will have already been wasted comparing labels...

I've found out that I am not a health conscious consumer... I'd rather eat what tastes better... after all, studies show that happier people live longer...
I'd rather die happily, one hand clutching my heart, the other a double bacon-and-mayonnayse sandwich, than dying peacefully in my sleep, a miserable old man who's only friend is his oat bran....
