I do recall, from triage scenario in DC, that the blood -being high in oxygen - is the first material to “decay” after death, taking with it the vessels that carry it.
It begins almost immediately.
When I worked at a funeral home based ambulance in the 70s, I was able to observe many autopsies and embalming procedures. Many large clots are pumped out of the body, some so large they needed to use a wire/hook to yank them through the neck veins. The video shows what’s saw back then. Those were my observations, and I am not seeing the connection with the WuHuFlu.
I don’t know what our veins and arteries are supposed to look like after we die but I do know that Dr. Ryan Cole is a board-certified pathologist with many years of practice and teaching on his resume. He would know what they’re supposed to look like and he’s the one bringing this to our attention. I think the massive clots are abnormal. Embalming a body begins with draining the blood and replacing it with a preserving fluid, so morticians would have to remove clotted arteries and veins in the exceptional circumstances that they find them. My understanding is that the problem now is that these are not exceptional any longer.
