The poor chap in question was unfortunate enough to suffer severe complications as a result of Covid-19 and required support in the ITU and needed ECMO.
The point that Gurnard made, and that you are so dismissive of guy_incognito is that this can happen to anyone and if the virus spreads out of control it will overload our already stretched NHS in the UK. Do you know how many ECMO beds there are in the UK? I suggest you research it, it might change your blasé opinion of what is a major health emergency.
