Dr. Rangan Chatterjee

Because frankly, a lot of doctors just don't have that.

Yeah, exactly.

We've talked a lot about the practical things that we can do for our immune system.

But I want to go back to...

One of the kind of main ideas in your latest book that I really enjoyed, what is the point of all of this?

Why should you make time to do these things?

What is the point of life and how we're living our lives?

And you kind of start off the book in quite a provocative way, don't you?

In fact, do you mind if I read the first few lines to you?

This is literally the opening to the book.

Let's start with an easy question.

Are you scared of dying?

Why did you start the book with that question?

Yeah, it's so beautiful the way you put that, Jenna.

And it's kind of interesting, you know, time and the passage of time is this underlying feature throughout your book.

And I'm just thinking back now, if someone had told me in my 20s to notice the daffodils, hear the birds, you know what?

In fact, my mum probably did.

And it probably went in through one ear and out the other.

I think there's certain messages that are right at certain times.

Do you know what I mean?
