here's another facet of the discussion that admittedly is rarely a concern but still interesting to me: what is the general pro-life stance on separating a parasitic conjoined twin? if it's undeveloped (sometimes they present as just a circulatory system with a partially developed central nervous system, or just a vestigial head etc) is it considered a "life" that should be preserved, even at potential risk to the viable child?
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger-all down here on Earth.
