Beks,
I wasn't ignoring your last reply to my comments, the forum wouldn't let me post to this topic the last few nights. I stand corrected. But I couldn't help but noticed that all three studies cited belong to that body of bogus "studies" carried out by medical folks I mentioned.
I waded through reams of those studies while in college. Believe me, they are a big rip-off of taxpayer funding.
