I mean, there's so much that AI can pull together to understand more about our individual risk.

And we're at the beginning of this journey of understanding it.

So we're really in the future going to have a much better picture of who is at risk of what, when, so we can screen better, we can prevent or we can treat things earlier in kinder and more personalized ways.

No, I think it's very true.

And people want to know what they can actually do to help themselves.

And one of the things that was critical to me when writing my book was I'm not a doctor or scientist, but I've traveled the world meeting some of the greatest people on the planet doing the most innovative work.

future of cancer, future of heart disease, lab-grown organs, so many different areas.
