So there's that, there's the impact, there's strength building, the muscles pulling on the bones, being strong so you don't fall, and then there's working on your balance as well.

So I thought that was a really useful way of breaking down the exercise.

There was something else that I thought was so lovely, which is that we still don't fully understand the role of dietary calcium and vitamin D. These things are not completely clear.

And so for listeners who are thinking, you know, but I don't drink milk, am I at higher risk?

It doesn't seem to be that straightforward.

If you don't like milk or you don't drink milk, you know, or if you're listening to this in China or Korea or Japan, when, you know, you may not culturally drink lots of milk, it does seem like we have...

Humans have managed to develop diets all over the world that give them enough calcium.

So we're thinking about, but you definitely, we don't need to be as dogmatic as saying the most high calcium food is necessarily the best for your bones, which I found really interesting as well, but there's still lots to learn.

I do think the one thing, Sergeant, did make me really think is I want to do a vitamin D episode.

All of that was very good medicine.

And if you're ready for an extra dose of calcium, then do check out this week's episode of Doctor's Notes because Sajan was kind enough to stay around with us.

That's right.

In Doctor's Notes, we're going to talk about osteoporosis, which is, I think, one of her main clinical interests.

I think that's right.

And we will do a separate episode on osteoporosis, but I think we can't talk about calcium without osteoporosis coming up.

That's right.

And Sargent also told us about how she got into this area of medicine.

And she talked a lot about bears and astronauts, which was extremely interesting.

So check that out.

That's all in the feed on BBC Sounds.
