Knowing that our software comes arunning - BDell555 says exactly the same thing I do but he gets away with it ( he writes in far better English than I, maybe why ). Not wanting to get him in dutch with you boys to be sure, but his stuff almost paraphrases mine - of course he probably never gets into the AIDS stuff - check out the average age of death for gays 39/AIDS 42 or 43/nonAIDS. Why the 43 for nonAIDS - let Mastcell mull that one over - put his medical research phd to some good use. He/you might want to check out the 39/42 vs 75+ statistical tests with one of your math friends, there are a couple of competent ones here on wiki.
