Ed,
Nothing to be sad about. I just make the point that I don't have an overriding reason to put in my head as an "I must live until then at all costs" date. I often see the comments of putting up with the side effects and issues framed in seeing the weddings of grandchildren, etc.
I have other motivations (quite a bucket list that I can't start on until I retire, which I am far too young to do with what money I have), and a lot of volunteer work. So no, I'm not going to refuse HT if it looks like a few rough months. But I will consider also that living a long, happy, and prosperous life requires a certain level of quality.
But even now, only with the RT, I am saddled with enough SEs that I can't go to a movie, or any event/place where I can't slip out quickly without warning to a men's room, and can't expect to make a whole day without getting socked by the fatigue wall. Those were supposed to be temporary, but they are now permanent. Just think what that did to my job environment. I'm not able to do the job I did before (and truly enjoyed), so for now I am doing what I have to do. So I am somewhat gun-shy of the doctor's promises these days.
