Katie Couric

So before we talk about what works, let's talk about what doesn't.

And I know you take on biohacking, pseudoscience, anti-science movements.

And all these things, you know, all this, I don't know, malarkey that's out there that is telling people certain things that just have no basis in science.

Why do you think, what has fueled these movements and what can we do about all this misinformation?

Well, let's talk about the tools because I know, uh, the, the new concept of health span versus lifespan has come into play and, and you write about that, but, but talk about particularly selfishly about women because women do live generally longer than men, but it doesn't mean that they're living well.

Um, but can you talk about this idea of health span?

Well, I was going to ask you about that because, you know, aren't there some genetic components?

Like you just are lucky in terms of

you know, your DNA and your genetic makeup that predispose you to living healthier.

It's like those people who chain smoke all their lives and yet they live to be like 95 years old.

So I guess the key is keeping your immune system strong, right?

And I always thought inflammation was caused, Dr. Topol, when the immune system goes crazy.

That's why immunotherapy is so tricky, because it's your own immune system fighting cancer.

But the question is, can you get the right balance where it fights the cancer but doesn't hurt the healthy cells and organs?

at the same time.

So what can you do to keep your immune system, I would say, in balance?

And someone's asking, Ira's asking about the microbiome, and Ira, we'll get to that in a second.

By the way, someone asked how you felt about the CDC vaccine panel getting shickhand, excuse my French, Dr. Topol.

And Dr. Topol said he, well, you say what you said earlier.

And think of all the lives vaccines have saved, right, Dr. Tobol?
