Doing
repairs
on
the
outside
of
a
rocket
in
mid-air
is
a
ticklish
job.
We
slacken
off
the
circulation
when
they're
right
way
up,
so
that
they're
half
starved,
and
double
the
flow
of
surrogate
when
they're
upside
down.
They
learn
to
associate
topsy-turvydom
with
well-being;
in
fact,
they're
only
truly
happy
when
they're
standing
on
their
heads.
The replay is still saving.
