Here’s something I’d learned about before, but didn’t really understand until nursing school:

When you put your hand on a hot stove (or any extremity on any major, unexpected source of pain), the decision to pull it away happens in your back.  That’s what a spinal reflex means–not just that the action is automatic, but that your brain isn’t even consulted.

You will never remember it this way.  You will always remember the event as “the stove felt hot so I pulled my hand away.”  But “you” didn’t do anything.  All you did was come up with a justification after your back had already acted.  Even if you know this intellectually, it won’t change anything–you still won’t be able to remember your hand acting on its own.  Your brain will not allow it.

There are more parts of the nervous system that work this way than you’d probably like to think about.

Alternate framing: your spinal cord (and indeed your whole body) is part of “you” just like your brain
