If ice didn't expand at 32 degrees there would be a very different form of life on earth.
Water
expands, under normal pressure, when it freezes into a solid as it
becomes ice. If water didn't expand at this critical point, ice would
be heavier than water and would sink. Ice would be at the bottom of
lakes and oceans and we would live in a world where only the surface of
oceans and lakes would be water. Water would probably be very cold and
most life would have to exist at close to the freezing temperature of
water. If life could exist at all.
How much of our lives have the perverse twist that water does of expanding at the critical point where it changes form?
I
would like to suggest that ice is an important metaphor about life.
From my experience, when humans make major changes in their life, at
critical points, it is usually for the better. Modern human societies
generally respond positively to people who take bold steps in the way
they live, work, interact, create, move, explore and behave.
That has certainly been true for me, in the modern world of commerce. I think ice may be a good metaphor to ponder. When you make a major change, make it a bold one.
