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.

And the way all these systems work is just amazing.

But no one told me that hormones have a role in this.

So in the research that I've been doing over the last 10 years, trying to tease out the mess, if you like, and going back to basics, I've read some very complicated, if you like, basic science papers where people have known for decades about the role of hormones in the brain and the body.

But I'm quite geeky.

I can read these scientific papers quite quickly because I've always got this sort of science background.

Most clinicians are reading guidelines and they're reading protocols for how to prescribe X, Y, Z. The scientists who are writing these amazing articles and many of whom I've spoken to over the years are

are never seeing patients.

So they can't sort of, they've not got this bridge.

They're just saying, well, this is so obvious.

Like we don't need to keep writing about it because it's been written about for decades, but that's been forgotten.

And then at medical school for many years, people have said, and they still do now, as you know,

well, hormones are so dangerous, you wouldn't prescribe those to menopausal women, and they're forgetting.

And this is where thinking about the role of hormones for people in their teens, in their 20s, 30s, 40s, and 90s, in fact, is so important.
