Question

How did George Washington die?

Answer 1

We do know that he passed away quietly at his home, Mount Vernon, on the cold night of December 14th 1799, at the age of 67, following a brief illness; possibly serious throat and lower respiratory infection.

But no one is entirely sure why or how he died

Here is something suggestive that I have found.
