The Job of a Narrator

I'm curious if there is something that people may not know about being a narrator. Iam honestly mostly just listening for my stomach to make a noise, like even ona casting level,. You are meant to sit and, like, not move, cause if you move, it could make noise. Am, and you're acting with your neck a lot, because you can't act with anything else. The biggest thing they don't realize about the job is actually have aly am, trying it can be. And i'm sure that it's very physically exhausting, specially when you do long stretches to record.
