And it's not just being physically and mentally well.

We need the whole picture, the companionship, those relationships, everything.

And it seems like a lot to ask for and dream of, but actually that's what makes us happy as humans.

And it's all very well to talk about AI and technology and what it can do for us.

We've got to make sure it does things in the right way that actually make us happy.

Yeah, true, and this is very much the case, I think, when people are talking about longevity because I've had quite a few conversations with people who are saying, well, you live all these terrible lives, all these terrible years of your life whilst you're trying to make yourself healthy later in life, and I'm shocked.

well, I'm not quite sure that's what's happening.

I think actually, if you're living healthily, you're probably feeling better at the moment as well.

No, well, when I went to film with Brian Johnson, this tech entrepreneur who's doing everything trying to reverse his biological age, he has now found love incidentally.

so that's good.

That pops his tics, so hopefully it's good.

His assistant, who has been working with him for years, but I think they seem very happy together.

But I left his house after the first time filming with him, and I was the first person to go and do an interview with him on his longevity regime.

So at the time, no one was familiar with this, and it all felt terribly exciting.

And I noticed that the whites of his eyes were so sparkly.

I'd never noticed how imperfect the whites of most of our eyes were, but they just looked so sparkly, amazing posture.

He looked like he felt amazing.

And whilst there was no way I wanted to fast 19 hours a day or be doing the exercise that looked like he's going to burst that he's doing every day, I left his house and said to my colleague, I really want to be a little bit like him because it looks like he feels great.

She was having none of it and said it looked joyless.

But I thought it would be nice just to take away enough that you could feel great without it being your thing you do all the time.
