And so that maybe, you know, makes it a little less likely that it happened.

Here's the thing that worries me.

If what we're talking about is Mars, so you're talking about a one-third gravity environment, not a weightless environment, a one-third gravity environment, I think the risk is, once we're talking about people who have lived their entire lives there, like a child born on Mars...

right, who then, you know, basically is, you know, growing in that one-third gravity environment their entire childhood, by the time they get to adulthood and are, you know, childbearing age, right, imagine a woman who gets pregnant and is going to give birth.

She will have had her bones losing bone density her entire life because her genetics are

the same genetics that we all have here on Earth, meaning that you're born with a certain bone density, but in a one-third gravity environment your entire life, you're losing bone density.

So her bones will have become more brittle and weak throughout her childhood and into her adulthood.

And now she is giving birth and experiencing the forces of the woman experiences during childbirth.

I think there's a real risk of fractures.

And we know that one of the parts of the body that's most prone to fractures from this kind of bone density loss is the hip and the pelvis.

And so, you know, the reason I bring it up is because that's a kind of a fracture that could actually be deadly if we're talking about it in the context of childbirth.

You know, that baby might not survive childbirth.

uh, the experience of, um, of childbirth.

And so what does that do then?

Um, you know, if we're looking about, you know, you know, the impact of this over multiple generations.

Yeah.

So one possibility is you just avoid the risk.

And so all births are done through C-section.

Um,

But that actually creates other situations because now if all the births are through C-section because vaginal births are too risky, now... You're selecting against women who can have vaginal births.
