No.

And so what we see in my lab is when we give an animal a disease, and we can do that, we can put in the human genes for Alzheimer's into a mouse, it has dementia.

When we reverse the age of the brain of that animal, we're not treating the disease, we're treating aging.

The disease goes away.

The body can heal itself when it's young.

So it's the aging process that reveals the disease that can be cured by reversing.

Because the cells are so healthy, they can fix themselves.

They can renew themselves.

The disease processes that cause these problems for us don't exist when we're young.

Why is it that a teenager rarely has a heart attack?

Because their body prevents them.

Why do young people typically not get cancer?

Because the immune system finds cancer cells and clears them out.

You and I have cancer cells in our body right now.

Why are we probably not going to die in the next year?

Because our immune system will find them and kill them.

But as we get older, we're going to lose that ability and we'll have a greater chance of having cancer.

In mice, which is where we live in my lab, where we work, it can be prevented and it can be reversed.

That's like the... That's the current theory.

The evidence that we have from my lab and a lab that I worked with in Australia...
