Omsigdavid, love at sixty is mature, much more responsive to the other's needs and comforts, far less defensive, much more appreciative of what we have (I guess because we know that our lives will end in not too many more years). We never forget to treasure what we have, we never forget to really look at each other, to hold hands, to touch affectionately, to cherish each other. I love knowing that this is the man with whom I will spend the rest of my life.
He had a stroke just four months after I moved to Colorado to be with him. I thought I had lost him and when he came home from the hospital, I wasn't sure if he would be the same Dys that I had fallen in love with. He was, with some changes in health and perhaps a minor slowness in remembering things that he had had at his fingertips before the stroke. I started a thread of the effects of stroke if you want to take a look.

Anyway, after that it simply became even more intense. It really hit home how fragile life is and how easily it can end or change irreparably. That is something you begin to understand as you get older, but it hit us in the face when he had the stroke.
Even though I have said that I wish we could have met earlier so that we could have raised a family, we both agree that it wouldn't have worked when we were young--for reasons I won't go into here, but defensiveness and emotional damage were the major factors.
Love between older people seemed absolutely boring to me when I was young. I guess it takes a lifetime to begin to appreciate just how beautiful it can be: it can even be thrilling, believe it or not. Even though I am not at all religious, I feel very blessed.
I hope that helps. It's a shame this question wasn't answered by someone far more articulate than I, but that's about the best I can do.
