This was an interesting read. From my point of view (I am 89 pushing 90) 60 seems very young. I know I was still working at that age and not even thinking about retirement. My husband was alive and we did a lot of travelling. After we both retired, we still travelled and did a lot of things together. Unhappily he died 2-1/2 years ago. So at 89 I feel that I will be alone for however many years I have left. We were together for 62 years and a part of me died with him. I do not seek or want a partner. I do have plans for a cruise with another widow, but even these small cruises are going to be harder to do as I age even further. I am extremely fortunate that I have nothing horrible wrong with me and I live independently. So I conclude that you cannot say at what point you will be alone forever. So much depends on what went on before, how old you are and especially how healthy you are.
