I see a lot of people who come in who were in fantastic health in their 80s and 90s.

So that's the message.

You don't have to be in bad health.

You don't have to have, you know, disability.

But that hasn't come out of nowhere.

Yeah.

So it's like doing homework all day, every day for the course of your life.

Both excellent questions.

We are testing for it more often, but it's not routine.

And people often need to ask for it.

So I think it's important, and that's why this show is important, to understand that this is part of a risk factor for conditions such as dementia.

And if you have alleles of ApoE4, as you mentioned, that means that you're less likely to break down the proteins that cause dementia in the brain.

Yeah.

And it's still working, but it's not working as well.

It's, I suppose, a comparison of, you know, 1970s, you know, Mini with a Tesla.

Yeah.

Or something like that.

Like, it's totally different.

But it is working to an extent.

So, obviously, if you do have APOE4, like Hemsworth showed on his show, that would put you at a higher risk.
