Katie Couric

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?

Okay.

But anyway, but getting back to longevity, thank you for doing that.

I just wanted that person to know that we had talked about that early in our conversation.

I think I was asking you, so if the immune system gets weakened and it's really important for us to keep our immune system strong, right?

Is that the key to aging well?
