I guess the fact that I'm not mildy surprised that people can be married for 60 years says something about how different our cultures are? Even though we're on HN discussing so many other things we have in common.
Divorce is rampant among celebrities in the USA. Maybe not worldwide?
It's not unheard of. But I guess it's a mix of several small factors:
1. divorce rates have been rising for decades.
2. 60 years is a very long time, and that means Dolly would have had to marry around 18-20. Marrying that young these days for my generation very much is an anomaly, and people are putting off marriage more and more these days.
3. Celebrity culture in particular has a much more tumultuous relationship. In a number of cases, marriage may simply be another influential tool to manage fame and wealth rather than an act of love and caring.
I think money, fame, celebrity status, etc. often creates pressures on the relationship.
Kind of like how it sometimes pushes people into drug addictions. That's a stereotype that we've all heard about since kids, but it wasn't until relatively recently that I thought about it seriously that it occurred to me that a touring celebrity musician's life can be stressful and the drugs can be (or start out as) a pressure valve release. I think that part of it clicked to me when I heard a musician being interviewed about it, I forget which. Maybe it was a Beatle talking about their early amphetamine days.
