Probably the closest thing I ever had to a near death experience was when I was a student athletic trainer in college.
Biggest, meanest player on the football team sits at my table to get his wrist and hand tape off after practice. I grabbed the scissors and with the first snip put a pretty good cut in the web between his thumb and index finger.
He yelped, blood started to flow, and I truly thought I was a dead man.
He looks at his hand, looks at me, says "You missed!" and stuck his hand back out for me to cut the tape off.
