“a hammer to the skull and brain surgery”
The brain can swell after a hit to the skull. Lethal pressure can build up. A hole is drilled to relieve pressure and I think it is mannitol that is given to reduce the swelling.
My aunt fell on her shower handle in 2009.
Don’t leave a hammer or knife out in the open. It can be used to kill you.
