We know that chronic pain, it turns out, is caused by exactly what I'm describing.

It's called the fear-pain-fear loop.

that you have some kind of fear, typically caused by actual damage, then that fear perpetuates pain.

That pain perpetuates more fear, which perpetuates more pain.

And so it turns out that we can actually create pain and suffering in our lives where it doesn't necessarily have to exist.

And that's psychological as well as physiological.

Yeah, yeah.

So I didn't answer your last question, but this brings it up perfectly.

What is the difference between fact, faith, and belief?

So a fact is an objective truth.

It is something that is true whether or not you believe it.

The world is more like a sphere than it is flat.

Sorry, flat earthers.

It's a fact.

Faith is a conviction that does not require evidence.

God rewards the righteous.

There is no amount of evidence that I can give to someone who has faith in that statement because no evidence is required.

Belief is somewhere in the middle.

Belief is not fact.

Belief is not faith.
