I think that left alone it is supposed to be around 13 or 14, yes. Not sure, but I think that's the case. But I think people are far from left alone here in the beautiful 21st century. And I think it has a lot to do with a lot more than hormones in meat. Again - not sure. I remember, though, seeing something on the news awhile back (a couple of years ago?) talking with a family who were veg, and ate entirely organic, used organic materials, etc., etc., basically did everything they could to avoid contamination, but they still had unreasonable levels of a lot of hormones and contaminants in their blood simply from living in this world. Sucks, right?
