I was a college student in the early 70's. That was about the time we first began to hear about "everything" causing cancer.
One of my professors had written a one page paper as a 'tongue in cheek' response to all the chicken little's. I have lost the paper but I do recall the opening line: "Studies show beyond a shadow of a doubt that 100% of all pickle eaters DIE!!"
Think about it!!!!!!
