That's the usual bogus claim advanced by people like yourself. Any specific health risk, other than someone with an MD saying, "It's just obviously, like, really really bad for you," would be an acceptable start toward shouldering your burden of proof.
ROTFLMAO....next time you choose a research topic, be willing to follow through! Instead of hoisting it onto others! ROTFLMAO...
PS Thanks for the laughs. It's good for my health! :)
