So we can look forward to much better tools for prevention.

on top of the lifestyle factors.

And then the other thing, to go back, Katie, to a point you asked about earlier, it's the AI that's so critical to tell us about the risk in each of us.

So are you at high risk for one of these three major age-related diseases?

And when?

We can never do that before.

We can not only say accurately if you're at high risk, but also when.

And we have 20 plus years for these diseases to take hold.

20 plus years.

If we can't do something in a 20 year time span with all these tools and with the ability to have such remarkable analytics, then we must be pretty dumb.

Well, you're right.

There's a lot of confusion.

But let me be clear.

Any sustained physical activity is good.

Any.

So even if it's a walk that's relatively brief without any fast heart rate or sweating, that's good.

But the more the better to a certain point.

It doesn't have to be extreme.

But we're talking about at least five times a week, ideally, 30 minutes of aerobic activity.

That would be brisk walks or cycling or elliptical or treadmill, running, jogging, all these sorts, swimming.
