I'm 76 and have had gut problems since I was, well, since I can remember. As we age, the light comes on: We're going to die of something. Believe it or not, one actually gets used to the idea. I was once young (yesterday) and now I'm old (today) and will be even older in the future. I'm only heading one way.
I'm sure we would all like to die of a blood clot in our sleep. No one wants to suffer and we are, after all, human. I've given up what I WANT and have accepted whatever it is that comes along. I just don't want a lot of pain or serious complications. Meanwhile, I'm trying to live my life and enjoy it as much as possible.
