Isn't weightlessness the obvious choice?

They involve biological bodies, atmosphere, and radiation shielding too,
all of which will probably be pass someday.

But you have to take baby steps.

This article is an interesting mix of sensible ideas (mostly in the
first half) and nonsense (mostly in the latter half). I have some
experience (and a degree) in neuroscience. If you have any evidence at
all that weightlessness causes "brains to develop with unusual vigor"
(whatever that means), please cite it.
