What are your thoughts on this woman's lifestyle?

A famous actress and dancer , 77, has lived alone for years after a 30 year open marriage. She says her marriage was superlative because not only was she best friends with her husband , they were free to have dozens of affairs throughout the marriage. For decades she has lived alone, traveled alone and prefers it to having a companion. When she sees a couple who has been married and faithful for decades she thinks to herself, “look at them; they seem spaced out and apathetic. Such a waste.”
She is happy with herself and her home on 75,000 acres, still writes books and is considering doing a movie. Her interests are numerous, she is at the head of a business and her home is “off the grid.”
Could you handle living alone, traveling alone and at no one’s beck and call? She does have a dog who is her “best friend.”
