I mean, I understand like there are some things that are below a clinical threshold, which maybe we don't want to worry about.

But how can it be that when we see are seeing so many more cases of something, it doesn't have any population level benefit?

Yeah, I've heard people say we shouldn't even talk about it as a cancer.

We should treat it as something else because the word cancer scares people into treatment.

One big question that I have about this, not just about thyroid cancer, but the question of what we can learn about the body in general, is if we look at the state of play now and we say, given the treatment techniques we have, given the screening techniques we have now, expanding our screening to the whole population isn't going to have a benefit.

Is that because we already know everything there is to know that is useful about such a disease or other diseases?

Or is it something about the limits of our screening?

in a future where we could zoom down, you know, have much more information about particular cancers, presumably more data would be good, right?

So what's the big problem with this particular full-body scan that we're talking about today?

Why is this an example of something that is going to give us information that is not useful, maybe counterproductive, as opposed to helpful to the people who are getting it?

Well, some people are taking it to a doctor, but also a lot of people are just monitoring it themselves, right?

And there's a conceptual shift that's happened where, you know, previously they had sort of assumed that they were in relatively good health.

They start to see some indicators that may or may not mean anything, but they've already stopped thinking of themselves as being in good health and started thinking of themselves, if not unwell,

unhealthy than on some spectrum of wellness and performance in which they maybe should be doing better, they should be addressing this or that, and whether or not those improvements will actually help their

well-being in the long run, they're already mindful of what they could or should be doing.

So they've already like redefined their measure of wellness from like, how am I feeling to what does my watch say how I'm feeling?

You're like really a late adopter.

I'm doing great.

You did have that feeling.

You didn't have the feeling of like, I know better than this watch.
