So there's lots and lots of things that older people or people with osteoporosis who are younger can do.

And if people are listening to this thinking, well, I've got a family history of this, I'm worried about my bones.

Is that reason enough to, if you're over, you know, if you're in your 50s, is that post-menopause perhaps, is that reason enough to go and see your GP and say like a bone scan?

Like what's the route into managing your risk?

Because it's symptom free until you break a bone, isn't it?

How do you spell FRAX?

FRAX.com.

And is that on the NHS website?

Gorgeous.

That's so great.

I mean, what a great thing.

So go to Frax, F-R-A-X, put it in, check out your risk.

What got you interested in calcium and bone metabolism in the first place?

Tell us more prehistoric animal stories.

Whoa, okay.

Wow.

And do people know that?

Because bears are able to gain almost half their body weight in adipose, in fat, and then spend the whole winter, they just burn their fat, don't lose bone density, probably don't lose much muscle either.

When you started with bears, you think, well, you're not seeing a lot of bears in your bone clinic, fair enough, but it doesn't feel immediately relevant to human life.

But actually, if you could understand that, it would be extraordinary for our human disease.
