That’s a really interesting point. I wonder if there are “artificial exohearts” or something that we could install on the extremities to keep vital body fluids

  Then you have to toughen up the internal tissues so that blood vessels aren't ruptured by high-pressure blood (which can cause strokes, permanent vision loss if retinal arteries are affected, etc). High blood pressure also affects kidney and liver function, amongst other things.

  > That’s a really interesting point. I wonder if there are “artificial exohearts” or something that we could install on the extremities to keep vital body fluids like blood and lymph flowing when the heart is not strong enough. Isn't that basically a g-suit, like fighter pilots already wear? https://en.wikipedia.org/wiki/G-suit https://en.wikipedia.org/wiki/G-suit Also, from that page: > The resting g-tolerance of a typical person is anywhere from 3–5 g depending on the person.

    Yes, but that tolerance is for seconds of exposition, not days.

    This is akin to the landing impact when you jump from something low enough that you won't die from it. You wouldn't survive it in a sustained manner, but the brief jolt, while maybe causing your innards to ache, is tolerated.

  Athletes already use compression boots which apply pulsed pressure to the lower legs as a sports recovery modality. But those are only used for maybe an hour at a time. I doubt whether they would compensate for the physiological stress of sustained high acceleration.
