Chapter 1: What is the main topic discussed in this episode?
On the podcast today I've got Lara Lewington who wrote the book Hacking Humanity. We talk a lot about AI and how that can improve our health and knowledge going forwards but the most important thing we spoke about today was the difference between lifespan and healthspan, how we can keep us healthy for as long as possible. It's something we all need to be thinking about doing.
So, Lara, welcome to the studio. Thank you. Great.
Chapter 2: How do lifespan and healthspan differ?
Lovely to be here. So I've met you a couple of times at different events, actually. Yes. And we met in Oxford at quite an alternative conference. Well, alternative for me because there's lots of marquees and outside, whereas I'm used to lecture theatres and very... They wanted to call it a festival. Yeah. A health tech festival. Yeah. It was lovely. It was a great day. So that was really good.
We were on a panel together and that was great. And in fact, you spoke, we had, was it five minutes at the beginning? We had to just, or 10 minutes, like really quick. And it was great because as soon as you started talking, everyone was listening and, you know, just your command of the stage was brilliant.
Chapter 3: What role does AI play in transforming healthcare?
But what you're saying is really important too. And then we met again a couple of weeks ago at another sort of longevity type event. Yeah, we seem to be doing the circuit of the same event.
But there are so many brilliant events now in this space. I think in the health and longevity field, finally, there are lots of get togethers where they're talking about real science, really interesting stuff. It's not the stuff on the fringes anymore.
Just for the listeners who might not know you, just tell me a bit about your background, if that's
Of course. Well, for the past two decades, I've been covering technology, spent 15 years presenting the BBC's technology show, Click. I've made numerous documentaries on health tech over the past few years for BBC, ITV, Radio 4. And this all culminated in the writing of my book, Hacking Humanity. Which is great.
I mean, it's such an achievement, writing a book.
It's a relief when you're this side of it.
But tech means different things to different people. Longevity means different things to different people. So let's just start with the longevity because it's a bit weird. I think sometimes when I talk about preventing disease and keeping well, because as a doctor, I was trained about diseases and treating diseases. Absolutely.
And that's kind of the thing which needs to shift. And we're increasingly getting the power to do that. So I think, first of all, your question on longevity, because the word can cover lots of different things. It can cover people doing extreme stuff, hoping they're going to live to 150 or whatever. I'm not interested in that side.
I'm interested in the problem that exists right now, that there is a huge gap between healthspan and lifespan. Women are spending a quarter of their lives in poor health, men 20%. We need to close that gap. And I think we have the AI and innovation to take us in the right direction to help us do that.

Chapter 4: How can wearable technology improve personal health tracking?
It doesn't cater for us getting the right amount of sleep, for switching off early in the evening. The food environment's really bad. Nothing around us is helping us.
Yes, there are plenty of exercise classes and gyms, but we're also all pushing ourselves to our absolute limits, which makes it really difficult because it's one thing to know what we should do to help ourselves, but another thing to actually be able to do it. It's not just wanting to do it, but being able to do it.
And the other thing is, you know, I went into medicine to obviously to help people, but I'm not here to help wealthy people get healthier. I feel very strongly that everybody should have a chance with their health. But it's become a real divide, you know, even just thinking about...
This is a generalization, but people that go to gyms are generally healthy because it's expensive to have a gym membership. To eat really good, organic, fresh food, it's harder. You go into areas of deprivation or you can find the takeaways. You can't find any fresh fruits.
No, and this is one of the big challenges in looking at future health. Because AI has the ability to be able to bring better healthcare to all, especially in the UK where we've got the NHS, a lot of the AI platforms that we're looking at are things that are being brought into the NHS. So just to put this into the context of actual things it can do,
AI could, for example, be an extra pair of eyes on a scan searching out tumors. It could be helping a doctor take notes to allow them to have the more human experience. Or it could be looking at micro movements in the face, changes in gaze pattern to be able to quantify depression in a way that no human ever could. So it can be lots of different things.
There are many trials in the NHS that seen these things are successful, but it doesn't necessarily mean that they roll out because not every successful pilot can. So the hope is that this is something that can democratise healthcare, make better healthcare for everyone. But obviously there are challenges because there will be access to some things for those who can afford it first.
And that is the sad reality here. And there are many people working in different ways trying to stop that from being the issue. For example, I was talking to someone who was talking about biological age tests. So these are tests that assess not your chronological age, but your biological age. And it's very, very early days for them.
So the idea being when they get better and more accessible, if they were to be subsidized and available at supermarket level, as this expert put it, they could be available in some of the most deprived areas where people need them the most. They would pay a couple of pounds for them. And this is to make sure there's adherence, because if people don't pay something, they're less likely to use it.

Chapter 5: What challenges do we face with increased health information?
There are plenty of self-help books out there, plenty of very good self-help books, but mine is kind of the book you need to read alongside it to tell you what you can really expect, what can you do for yourself, and what can the healthcare system do for you?
Because we're at the beginning of a real shift in how this is going to work, because things can become far more personalised, even when it comes to our activity data. We can see through long-term patterns if there are changes. It can recognize, are you tired or unwell?
It can see for women, the hormone tracking, being able to track by temperature and having that period tracking can be really useful because when things do change, you start to see those patterns. And whilst they're not medical devices and you can't diagnose with them, there are lots of people who have felt something's amiss, gone to a doctor and ended up being diagnosed with something serious.
Changes can be meaningless, but they also can sometimes represent something that needs looking at. So this ability for 24-7 data is something that's going to become increasingly useful, also built into the bigger picture of all of the other data that we can collect on ourselves.
Yeah, and I do think the tracking is really important and it's quite individualized as well. But, you know, on the other side of the coin, I'm in a group with some doctors who absolutely hate this. They hate the fact, as I'm sure you've probably heard from others, they hate the fact that people wear wearables.
They think it's terrible because they think people are being overdiagnosed, that there's all these worried well people. But I think it's all again about education as well and what you do with the data. Well, that's absolutely it. It's so important, isn't it?
It really is. It's understanding what the data means. There are a whole load of postal kits that we can all do with DNA tests, all sort of blood tests. But we need to understand what the results really mean. Where is the science right now? We can all sequence our genome for a few hundred quid. It would cost 3 billion back in 2003 to sequence the first persons.
But there are only very small elements of that that are meaningful to us right now. And for many people, they're going to end up with pages and pages of data and be utterly confused. But for the people where there is something important, and one expert described this to me as how we should go with the grain of the healthcare system we're in.
It's really difficult, but then also it's knowing what you do with that information. I remember many years ago, one of my patients had Huntington's disease, which is usually an inherited condition. it causes some unusual, it's a movement disorder and it can cause early dementia as well. And the movement that people get, you can't control the limbs and it can be very distressing for people.

Chapter 6: How can we democratize healthcare through technology?
Oh, that might help then.
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. And obviously, most of us have jobs and busy lives, and that is his job doing that. So we can't all do what Brian Johnson's doing. But all of us have sort of limitations as to how much we can fit in. You know, it's often a squeeze to fit in the exercise before work.
And if you leave it to the end of the day, then you're too tired and don't. And we have real life challenges. And when it comes to sleep, it's great if you can get it, but not if you're an insomniac, have small children, are caring for someone, or...
just a busy yeah yeah absolutely and it is being realistic it's it's so important but I think we can all be honest with ourselves and think about things that we could do and but make the difference now not thinking about in a few years time or once I get diagnosed with arthritis or if my blood pressure goes up then I will do I think we have to be have real ownership for our future health rather than any diseases that might come and it is changing the way that we think isn't it
Yeah, definitely. And I think people are very conscious of the fact that they can't take on every challenge. You can't read an article of these are the best things that you need to do to look after your long-term health and go away and do all of them. But there's little things you can take away. There are the little things that stick with you.
It's like you read a book, you come away with a few takeaways that you actually put into your life because they're the things that work for you.
