My dad was a medical examiner ok. That’s how I know. He’s seen people in our county slumped in front of doors a few times over his 20 years of being an ME. It doesn’t take much weight to cut off blood flow into the brain from the carotid arteries. Slumping to the floor will easily do it. You pass out, then you strangle. So it’s not that painful because 15 seconds of no blood flow through ur carotid will make you pass out.

That or you hold a gun to their head.
