I just don't get -- or agree with -- the connection you're trying to make, on several grounds.First of all, that "nurturing" males get more IBS. That one seems far-fetched. When women get IBS it has to with their hormones, not their nurturing natures -- and the reasons males get IBS is still rather more a mystery.2/And several things specifically about JFK. What is your definition of "nurturing?" You mention one who would "befriend" rather than "fight or flight." One doesn't think of the Bay of Pigs Kennedy or the tough Civil Rights Kennedy this way. JFK was certainly one of the more compassionate among our presidents, but I doubt many could say "nurturing," with its feminine connotations, was the predominant side of his personality. Tough, resolved, brave and stoic -- with the fairness, kindness and decency all the Kennedys share. Unless you have special knowledge of him, I cannot see where he falls into that special category of "nurturing male" that would prove your theory. I wonder where you are getting this from?3/Healthy males without IBS also have "nurturing sides." Clinton adored Chelsea and was very playful with her. He has no IBS. Jimmy Carter. He has no IBS. I could go on and on.
