Heart Attack !
A friend of mine died of sudden heart attack a few months after having Covid really bad. Before it was known to the world. He threw a clot from his lung to the heart and was found dead at home. He was very fit.
Now that we know more, if early treatment with therapeutics were accomplished, tissue damage would be minimized and events like what happened to my friend or this Congressman would not take place.
By the time one gets to a ventilator it is too late. It’s like an F-35 or F-22 flying to the merge, should not ever happen.
