It was a fascinating study in the laws of physics.

It involved an unexpected forward momentum on ice, a collision, the entangling of the two skate blades, a loss of balance and the fall onto the cold hard surface.

As you might expect, gravity played a starring role in this episode.

My feet went out in front of me and the brunt of the fall was taken by my tailbone and left wrist which tried to break the fall.

While my back end has never met directly with a steaming locomotive, I know this is more or less how such an event would go.

Or to put it another way:

Ice + gravity + human bones = Yee-ouch (!)

But ice was also my salvation later that day. My little Florence Nightingale typist wrapped and iced my wrist. When the throbbing worsened last night, Ibuprofen did the trick.

This morning there’s a dull ache in the tailbone and there’s a sore-but-not-throbbing wrist.

The good news is that I’m still typing, so today’s work deadlines will be met.

Oh cruel gravity.
