I think my favorite of these is to brush your teeth. What we've discovered is that people who have worse oral health actually have a higher risk of heart disease. There's maybe even a link with dementia because the bacteria that cause gum disease have been found in the brains of people who've got dementia.

I mean, that's exactly right. And I think one of the big challenges that I've overcome is to explode people's conventional wisdom about what aging is. But what I mean by aging as a biologist, actually, the simplest definition isn't a biological definition at all. It's a statistical one. And it's simply how fast your risk of death increases with time.

As a human, our rate of aging as a species is that our risk of death doubles about every eight years. So let's try and put that into some kind of context. I'm 36, and that means my odds of death this year are about one in a thousand. And actually, you know, I quite like those odds. If that were to continue for the rest of my life, I'd live into my thousand and thirties on average.

If that were to continue for the rest of my life, I'd live into my thousand and thirties on average.

But of course, that isn't what happens. My risk of death will carry on doubling every eight years. And so that means if there are no advances in medical science between now and me, you know, fingers crossed making it into my nineties, my odds of death by then will be one in six per year, life and death at the roll of a dice.

And so, you know, as a biologist, you look at this and there's this exponentially increasing risk of death with time. That is the problem that we call aging.

Yeah, I guess you've got to look at that as 0.1%. And actually most of that, when you're my age, is still down to external things. We call them extrinsic forms of mortality biologically. So that's things like car accidents and unfortunately suicide is a really big cause of death for men at my age as well.

So it's not generally the sort of cancers and the heart disease and that sort of stuff that you associate with older age. It's the external causes of death. And then obviously as you get older, the risk of diseases increases and starts to swamp those external causes.
