Does this have anything to do with Ken's comment about
biology is all about surfaces? I'm still thinking about that one.

This one is more complex. But, in a nut shell, biology is about
structures in liquid. and stuff is happening on the surfaces of the
structures. But it could've been a different liquid than water.

Just to push the "nut shell" analogy a bit further, because of the
hydrogen bonding of water (which is also responsible for its freezing
behavior), long chain aliphatic compounds (oils) are not soluble. But
if you make a molecule with one part that hydrogen bonds and the other
part a hydrocarbon tail, then you can make bilayer membranes. These
are the structures that provide the surfaces for biology.
