She drew the short straw and turned out to be genetically susceptible.

Unless I'm missing something the heart monitor isn't evidence of that. It may very well be that she's following her doctor's overcautious advice and showing off on social media to contribute to the fear mongering. When I got it last month they told me to monitor my blood oxygen levels if I happened to have something that would allow me to do that. I didn't bother because it was just a mild to moderate cold with a few extra symptoms in my case. Miss Valkenberg's incessant need for attention makes this theory of mine very likely.
