bottom up rather than just plowing through the noise and saying HRT is really good when it's body identical.

It's like, let's go back and see how it works.

So I've got a big chapter about inflammation because as you know, with all your research for your books, inflammation is crucial for keeping healthy and it has to be a balance.

We need a bit of inflammation to keep us protected, but we don't want too much.

And if we don't have enough, we're exposing ourselves to not just germs, but diseases as well.

So people understand inflammation.

And then there's a lot, like I say, about the brain and how that works.

Because, again, if people can understand basic physiology and how these hormones have their roles.

then it's easier to unpick some of the noise and the mess that's going on out there about whether hormones are good or bad for you.

It's really strange, isn't it?

Because I did a lot of really good basic science in the 1990s when I was at medical school.

And as you know, I took a year off and did a pathology degree.

And I spent most of that year learning about the macrophage.

And that's why I love it so much, because it's such an important immune cell for us.

But no one taught me about the role of hormones with these.

We learn a lot about all the way the body works.

And it's a marvel how the body all works together.

Nothing works in isolation in our body.

And so I spent a lot of time, for example, and I've written about it, about the cardiovascular system, about the control of our blood pressure, our endothelium, the lining of the blood vessel, our conduction pathway of our heart.

There's a system called the RAS system, which is our renin-angiotensin-aldosterone system, which helps with our fluid retention and helps with our blood pressure control through the kidneys.
