I gotta tell ya firebrand, when I hold the photo of an ultrasound taken at four and a half months pregnant, next to a photo of my one week old grandson, I would have to disagree. There is no mistaking that they are the same person. The experience really changed many of my thoughts on these type of issues.
OK, but do you get the point I was making? Change "six" to "three" if "six" bothers you.
