I looked up how hitting your head can kill you. This was one of the possible ways:
Trauma to the brain may also cause a haemorrhage, or bleeding inside the skull or brain. Without immediate treatment, this condition is deadly, as is a hematoma, or blood clot, that forms from the escaping blood.
What other stories have we heard about brains bleeding and clotting lately?
As someone who has had 5 concussions the head and brain can take a lot.
The clot shot and falling down or getting whacked by someone you pissed off seem likely. It takes a lot of force to cause that.
