Keep Your Eyes On The Son

Why don’t trees freeze to death in winter?

After all, if you or I stood outside naked for several months in sub-zero temperatures, we’d soon be turned into frosty statues.

Trees can’t burrow into the ground and hibernate like bears, and they can’t fly south like migratory birds. They’re fixed in place, at the mercy of the elements.

And yet they somehow survive through the cold depths of winter. Why don’t they turn to ice, since, like other living things, they’re made mostly of water?

Their trick is something called “hardening.”

In autumn, trees in cold climates undergo a change whereby water flows out of their cells. The concentrated sugars, proteins, and acids left behind act as a potent antifreeze. The water now in the spaces between the cells is so pure that ice crystals can’t form. This ultra-pure water can be cooled to -40 degrees F and still remain an ice-free liquid.

Pretty cool, isn’t it?

But what is it that triggers the hardening?

Ah, this is where we can learn a lesson from the trees.

If We Could See Our Words

If you live in a warm climate, there are a few things you’re missing out on.

One of them is the ability to see your own breath.

(You’re also missing out on high heating bills in winter, backaches from shovelling snow, and frostbitten fingers, but I think you can do without those things!)

Why can we sometimes see our breath in cold climates?

With the combination of cold outdoor temperatures and the right humidity, your breath condenses as it is exhaled. It then appears as a misty cloud being emitted from your mouth.

It got me thinking: wouldn’t it be helpful if we could see our own words, too, and not just our breath?

By that I mean, if only we could see in physical form how our words affect others, we’d think twice about what we say.

If words came out of our mouth visibly shaped like the weapons they often are, we’d probably be horrified. If we saw what appeared to be daggers or fists hurtling toward the other person, we’d want to take back what we’d just said.
