Is that true?

Yeah, I do a biphasic sleep cycle.

Really?

Yeah.

I guess it works.

It works, yeah.

It happened during hiatus.

I was not sleeping well and I was getting really pissed off.

And so I was like, if you're going to be up, you're going to work.

And I actually got a lot of work done, went back to bed, woke up, started my day, had a whole day's worth of writing.

I mean, you look pretty good.

I feel okay.

I fall asleep driving here sometimes, but other than that, it's okay.

Part of what makes this show work is the versatility, right?

Obviously, the medical stuff and the injuries, and you see it all, and you guys have done a great job with prostheses and all that jazz.

But there's AI in season two, and there's the Medicaid cuts in season two.

There was the measles outbreak, right, in season one, which you guys were, I think, ahead of happening in actual real life.

Clearly, you're thinking about real-world stuff as you write this show.

Well, what happens when we talk to the experts, regardless of what field of medicine they're in, we talk to them about what scares them, what keeps them up at night.

And then when we extrapolate where things were going, being in the head of the measles epidemic was not being overly prescient.
