My bad...though couldn't we develop some anti-G shield?

There are things that can be done to increase human G-tolerance.
Lying flat gets you to 20+ transient Gs without serious problems,

As others have pointed out, anything mechanical that you can
harden a lot (artillery shells take tens of thousands or 100,000 Gs)

People... should ride gentler things.

If cryogenics is finally gotten working, then that incidentally solves
that problem, at least a bit.

'Cryonics,' not 'cryogenics.'

And it's at least not forbidden by the current laws of physics that
we know, just lots and lots of apparently insoluble chemistry and biology
problems.

True, but....

I'd imagine a astronicle could cope with at least a thousand G.

Why?

There's already a signifigant problem with microcracking in the
bodies of suspended cryonics patients:

The hope is that nanothecnology or something similar can make the
repairs in the future, but one would prefer to minimize them to begin
with. Why also subject the body to accelerations that would encourage
this?
