My own belief is it is a 70/30 split. 70 percent KNOW...and they are being paid off. I use to work in the medical field and things hit me really hard when a doctor I worked for said he would prescribe heart medications to ppl that didnt even need it if the drug company would make it worth his wild.....the medication he was talking about was known to have some very bad side affects also....bye bye florence nightengale.....
