[ExI] Could humans live on any other planet?

[Brent Allsop]

I think this is all absurd and clueless thinking.  We'll be able to
re-engineer our bodies, and all life, long before we are traveling to other
stars.  Helloooo.

We shouldn't be going to space, mars, and even underwater, till we can do
so without space suits (and till we have multiple restorable backups of
ourselves...).
