First it turns out that eating kosher is actually a pretty damn good way of staying healthy and avoiding food-borne illness (come on, Kashrut tells you to bleed out your meat before you cook it and to never eat shellfish – for a desert-wandering people three thousand years ago, that was quite an astute judgment), and now THIS:
“Circumcision may stop millions of HIV deaths – Significantly lower infection rate among circumcised men, W.H.O. study finds”
After so many coincidences – who could have guessed that Kashrut was actually going to keep people from dying of food poisoning, or that circumcision was a way of preventing disease back when they first picked up the ritual? – you have to wonder if the tribes of Israel weren’t being given a few hints here and there.
