I seem to recall research studies in the past in which at least them married men, if not also most of the women, seemed to live longer than their single counterparts. I am guessing that the cause for that is that women tend to be more nurturing in general than men and so the married men's health tended to benefit from that. I think most of the studies concluded that married life was equally stressful and beneficial for married women, so they didn't get as much of a longevity benefit as the men from marriage. These theories and trends seem to match my experience from my one marriage, which seemed to improve my own health until my wife became ill and then the stress of that began to affect my health. I don't want or feel the need to get married again at my current age with no kids, but I sure would like to find a committed relationship sometime in the next few years. I know that I am healthier and happier that way as long as it's not with someone that is wrong for me, which is always worse than being alone....
