But if it's something that you're worried about, then I definitely would have a look.

And one thing about bones is about 80% of our bone mass is genetically determined.

So if you know, okay, my mum had osteoporosis, my mum fractured a hip, my sister's got this, my brother's got this, it might trigger you to look more closely into what you're able to do.

So for that remaining 20% of bone health, it might influence some decisions you make and some things that you do.

In terms of bone health, one of the key things is how to enable people to reach their peak bone health.

And that happens very young.

It happens around age 25.

Really?

Oh, we've missed it.

So what happens when you're growing, when you're young, we're growing our bones.

So bones are getting bigger and longer, but they're not fully mineralized.

They're not strong.

So as you get older, as you mineralize the bones and they stop growing and then they get stronger, that's when you reach your peak bone density.

And that happens at different ages for different sites.

So at your hip, it happens around age 20 and at your spine around age 25.

So good nutrition, sunlight, not smoking, not drinking, all those things that will help your bone health and to help you... And impact?

Impact.

Exercise is really important.

Okay.

So you reach your peak bone mass, and then you level, you have a plateau.
