Well, I think it's important to know because they're the stages that we should be aware of and you can do something about it.

And that's what we'll come on to, I expect.

But, you know, this isn't all not in our control.

About 20 to 30 percent, our genes are dictating and we can do nothing about that at the moment.

But the 70%, that's like two thirds of it.

We can absolutely control or at least modify significantly.

And that is a lot.

So what is happening at those stages then?

30, 50, 70?

We don't know why it's happening.

That's the first thing.

Certainly hormones are involved in women around 50, et cetera, and possibly 30 also.

But we don't know what the trigger is.

We don't know what the key is that's unlocking that and causing that acceleration of the aging process.

But we do know, if you look at the cells, that you can see a speeding up of inflammation in cells, for example.

Inflammation is probably the key common pathway that leads to cells getting more sluggish and

ultimately dying, which is what aging is about.

Now, we all know about eating well.

We know about exercising and we should step up our exercise as we get older, not pull it back, which is sometimes the temptation, I think.

Yeah.
