Maybe there is more to consider here, my friend is 5 years younger than her partner of 69 who has resorted to being a typical old man, happy to potter along, watch TV, rise late, spend ages in his dressing gown, not interested in holidays, days out, meals out etc. She now finds him boring and has said that he would be happy in a retirement home seeing out his life being cared for with little to do. She is healthy, still works, has a circle of friends and really dreads the days, especially Christmas holidays cooped up with him. They have dogs but he never walks them or goes out with her when she walks them. So it's not just about being a carer when health issues arise, it is also about life and living that you need to consider.
