Most older people that don’t have Alzheimer’s or dementia are quite aware of their mortality.
We will all get there someday, but I certainly have a lot of respect for those older people that are able to handle aging with so much grace.
It really isn't just about mindset! Sure, that will have something to do with it, but it's really a minor part, and even then, it will be much much much harder to have a positive mindset there then in a college dorm. (Again, I'm not saying it's not possible - I'm really just trying to make people empathize with older people that don't want to go into a retirement home. I think that it's a really reasonable thing not wanting to go there)
When you are bored a large percentage of the time, you seek ways to alleviate boredom, such as going to events, hanging out with friends, hosting parties, etc.
I think a lot of people don't realize how boring life was as early as the 1980s for most people. I can't imagine how boring things were prior to that.
Another reason is just the fear people have today, facilitated by the news and politicians. I'm sure it plays some sort of role. There was a lot of fear peddling in the 1980s too.
if this example is from the book, I guess I just lost my interest. Totally different scenarios, apart from "living with other people"
