I think about behavior change in two levels.

There's, you know, tricks for habits, right?

Make it easy, stick it onto an existing habit, you know, design your environment in a way that supports the behavior you want.

Those things are very, very helpful.

And I think there's a much deeper level to behavior change that we don't think about enough.

And I really strongly have found that

people's behaviors will always end up matching the person who they believe themselves to be.

So you can try every January to change things, but if you don't fundamentally change how you see yourself, how you value yourself, as you say, living in alignment, you may find that that's the reason you can't make these habits stick because there's a slight disconnect.

Your behavior matches your beliefs.

You know, how you view yourself, the identity which you hold has certain behaviors that are attached to it.

The only way, you know, and I think...

this doesn't get spoken about enough because it's much easier to talk about, you know, little tricks for habits.

And I do as well.

And they're helpful.

Up to a point.

We'll come back to your personal story maybe a bit later.

I do wanna talk about practical things that people can do when it comes to improving the health of their immune system.

Because as we've already said, the immune system sits at the heart.

are probably everything you want from your health.

You can make a case that good immune system health is necessary for that.
