Interesting if irrelevant thing: when the missus miscarried one of our triplets, we were told the other two had also died. The good woman did a deal with the Lord Buddha that she would give up eating beef for the rest of her life if the two were OK. Lo and behold, visit to the hospital, two heartbeats and a couple of months later both were born more or less healthy (some heart problems that resolved themselves). I don't really believe stuff like that, but one thing is for sure. I'm not eating beef any more. Just in case.
