actually i bet you do have 30 friends that take something that not only has many studies proving it's toxicity to humans but has never been certified by the fda as safe. i bet most of the people on this forum take the same thing. twice a day. maybe more.
how does one go about getting people to take toxic chemicals and think that it is good for them? turn on your tv. you'll see ads for it every day. also in every magazine. seventy plus years of indoctrination.
