ELI5:is passing out from pain equivalent to a circuit breaker?
gpt
It's a poor analogy, but it works nonetheless.

Many people pass out because of the vaso-vagal response. Their heart rate slows to almost zero, blood pressure drops, eyes roll back, they sweat, get pale, and pass out.

This can happen from something a simple as placing an intravenous line.

Passing out during torture or other horrific experiences ~~I'd~~ is probably more akin to what you're referring to in your circuit breaker analogy.
