Two of these were ruptures that required emergency surgery and one just required relatively immediate, but planned, surgery.
All are as confused as I am by the sudden shock and of course grateful that they were in urban areas (Bangkok, Thailand and Baltimore, USA) with big modern hospitals that took them in, checked them out, and did the necessary surgery to save their respective lives.
Each is fine now, though they probably would not have been 300 years ago if that same thing had happened.
Is this a common occurrence? Apparently, more so than I'd thought.
