I don't get that.
But Eric, can we talk about the Farsight cartoon with the sheep exercising on the treadmill in New Zealand?

So another, I think, huge misnomer or misrepresentation by some that when you exercise, you turn on fight or flight, true, and you turn off parasympathetic, false.
You don't turn off rest and digest when you turn on fight or flight.
You don't turn off fight or flight when you turn on rest and digest.
This is everywhere on social media and there's no evidence for it.
I mean, it's a totally subjective thing how you feel.
I feel rested and digested.
I feel fight or flight.
But that doesn't have anything to do with what is happening in your nerves.
