Dr. Rhonda Patrick

And that is, if you think something bad is going to happen to you, if you're a 49er and you're like, this story comes out, my teammates are getting these Achilles tendon tears, oh my gosh, it's this facility, and you think it's going to happen, you can actually cause bad things to happen.

And there are trials showing about this.

This is a real thing.

And again, it goes back to that personality type.

There's actually genes that are linked to a placebo effect.

and genes that are linked to a nocebo effect.

It's the pessimistic viewpoint versus the optimistic viewpoint, right?

And that's really a phenotype.

It's a personality trait.

And so you're absolutely right.

If these football players are thinking perhaps that this is going to negatively affect them, your body makes inflammatory things.

You make oxidative stress.

Your brain controls that.

And so you can make yourself more predisposed to terrors and stuff because of the inflammation generated from the nocebo effect.

No.

Never.

You can always find something negative to focus on.

And that's the bottom line.

The right person to really answer this question.

You would probably talk to someone like Dr. Arthur Books.
