Since joining this site I have noticed three things: 1. Some people just can't get enough of circumcision. 2. Some people can't keep themselves from getting nasty about it. 3. Some people just looooove arguing over correlational studies that have no way in hell of proving causation, and are therefore relatively useless in the scheme of medical research. Therefore I propose the following as my contribution to keeping this incessant dialogue going: Since most men in the USA get circumcised, and since the USA is the "fattest nation in the world", there is therefore a positive correlation between circumcision and obesity. Furthermore (!) circumcision must, therefore, forsooth, CAUSE obesity. P.S. to any stat heads out there: Any thoughts on the sample size we would need to achieve the power necessary to get that correlation and get it published in a peer-reviewed journal?
