Hello, welcome to What's Up Dogs.

Zandi, have you had any milk today?

I had some in a cup of tea.

My son Rex starts every morning with his bottle of milk, and that's how he gets his calcium.

I'm pleased you brought it up, Zandi, because calcium is, of course, what we are going to be discussing today.

The fifth most common element in your body...

We're going to be finding out more about what it is beyond its place in the periodic table.

We're going to be finding out how it works in our bodies and whether we're all getting enough.

Before we get into the main topic, though, I haven't seen you for a week.

What have you got for me?

What I've got for you, Chris, is 25 kilos of oats.

These were not ordered by me.

So my wife, Dolly, ordered oats.

And when they arrived, it was a 25 kilo bag.

Not lots of little bags, like a massive, the kind of bag you'd see on a farm or maybe at a stables or something like this, like enormous bags.

And she's got form in this area.

So when she was in her early 20s, she wanted to buy a nice shirt on eBay.

And she saw one, she ordered it, and it was in her size.

But the size was actually a kid's size.
