Then we could all hibernate all winter.

Sword of the dream.

And if the astronauts in space are doing this, I mean, astronauts know about this.

This is famously a problem.

The Russian astronauts who are out there for a long time would do their crash landings and break bones, wouldn't they?

Are they able to offset this by, I don't know, using elastics and treadmills or...

Can you combat the effects of microgravity?

I think it's very obvious talking to you.

You've brought up bears.

You've brought up fish evolution.

We've talked about astronauts.

We had rhinos.

So maybe bones are where you end up if you're interested in kidneys and livers and sunlight and skin and fish.

And evolution.

You're interested in complex systems.

Is that right?

Sargent, it's been such a joy having you on the podcast.

Thank you so much for joining us for Doctors Now.

Thank you.

What struck me about Sargent's description of her area of expertise in her field is that she thinks about the body as this very complex system.
