How vulnerable are the kidneys?
How vulnerable are the kidneys? Wikipedia seems to indicate that they're pretty well protected. And is a punch to the kidney a harbinger of certain death, or just a painful internal injury?
Honestly you could have done a search here, or used google a bit more. There's plenty of documented info about kidney shots, and video footage.
It's a potential pain-induced KO or knockdown if the kidneys are hit hard or repeatedly.
Will do, then. Thanks, and sorry.
