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.

Frostbite wouldn't be nearly as much of a problem if
we weren't water based. The problem is that when cells
freeze, they burst their membranes and die. What if freezing
was non-destructive, and things could just thaw back out
again?

There are organisms which can survive freezing and thawing.
They must use some such strategy. Viruses don't have any
water. But bacteria do... how do they survive? Or do they?

I remember reading that some bacteria have a natural antifreeze in
their system, allowing them to get to much lower temperature before
freezing. Also, bacteria can form spores (which are dehydrated), that
sounds like a useful coping strategy.
