There is also a lot said about morticians finding long strings in blood vessels. Might be a mistake (playing into commie trash defense) calling them clots. It appears that they are made of long chain proteins that circulate but do not form into “solids” until the body cools after death. Kind of like jello.
Nonetheless, what they do to living host is unknown, in addition to why they are not removed by liver/kidneys.
“Kind of like jello.”
Black pudding :)
