Diet Juice

I saw my co-worker drinking "diet juice"(less sugar,more fit) today and I got really surprised by the fact that she is buying into this funky concept.(she definitely has no diabetes)

To me,the "diet coke" works because of the artificial nature of an orginal coke.But "diet juice" doesn't work because the "juice" is born to be "diet".

Just because there is a market for "healthier drinks" doesn't garante this is a good concept.
