My parents are in their mid-80s, and I spent quite a bit of time with them last year. I don't see what mecurtin did. We actually had a very frank talk about intimacy because they were interviewed by someone studying long-lasting marriages and they passed on the survey/results. For example, they are no longer physically able to have sex (which they are not pleased about) but they cuddle A LOT. They also had bad health issues last year, and when they were separated (e.g. having to be in the hospital, or in rehab) they did poorly - being back together literally helped them heal. They both sleep a lot more (naps etc) than they used to, and also have difficulty sleeping through the night. They both are acutely aware of their memories and cognitive abilities sliding (they were both scientists). They have both recently had health issues where they needed wheelchairs for extended periods of time (months) but now my father only uses a cane and my mother uses a cane or a walker depending on how far she needs to go.
