Wow, surprised, and yet not shocked as it just makes sense, and it's time. She worked hard for lots of years. She's also enjoyed a lot of travel through her business in recent years, by taking groups and promoting the travel agent who set up the trips, thereby probably a business write-off, and free trip for her. All to say...she's made the most of the business...lived well doing it.
She's in her late 50's, from all appearances has a healthy nest egg. I hope the marriage is a successful, happy one, and wish her the best. She's lived in the limelight a long time. Having a more "personal life" now just sounds right to me...Good for her.
