Huh?

is where the real speed can
be obtained, up to perhaps 10%'c' seems doable, or at least until you
run yourself into a speck of sand or just overheat from the ISM
friction of Vt/slug factor of perhaps as great as 1e9 atoms/m3 or even
as little as 1e6 atoms/m3 is somewhat testy if having to displace your
large craft and yourself within through that nasty muck at 3e6 m/s
without becoming a comet that's losing it's cool.

Perhaps evolving into having an exoskeletal body is best for such space
travels.

How does that change the fact that I want to be able to ride
something powered by a high thrust engine, without wondering if what's
left of my *endo*skeleton will collapse?

Remember, I said 'get somewhere in space in a reasonable time.' This
means high thrust orbit departure, and insertion at the far end. And if
I'm around when we get fusion and/or antimatter nuclear thermal rockets,
there may be respectable acceleration/deceleration over most, or all of
the trip, too. Preferably at 1 Earth gee, but to someone that's totally
microgravity adapted [whatever that may mean], even .1 gee may be too
much. I don't want to be that someone.

(Okay, now that I think about it, you *could* keep that someone in a
water tank at signifigant acceleration times, but still...)
