"Last weekend, a 22-year-old man and a 20-year-old woman went overboard from the Grand Princess. They were found four hours later 150 miles off Galveston, Texas. Neither was seriously injured, and they asked the cruise line to keep their names and the circumstances that led to the fall private."
I think they went for a late-night run around the deck and were confused when their Forerunner said their current velocity was 20 knots.
