 Because a lot of that comes from an aneurysm. Not all aneurysms are detected. It doesn't mean like Joe Biden had years ago where they had to do an emergency surgery where they cut into a skull to stop the hemorrhaging and bleeding in his brain. Then once they closed it up, he chose elective surgery because he was still slightly bleeding. They had to cut open the skull again, go in, totally stop the bleeding. And he seemed to be okay.
