Today's interesting fact has to do with yawning.
Yawning is contagious in humans and other primates.
If any primate sees another yawn, the odds are it will also yawn.
But with humans, the contagiousness of yawning greater.
Not only can we humans yawn when we see other humans, dogs, cats, or primates yawn, we also can start yawning if we read about it, write about it or even just think about yawning.
As no other animals has successfully learnt to read, humans are unique.

Today's interesting fact has to do with Global Warming.
Not the global warming that is being discussed today, with some stating that it doesn't exist and others stating that it does. But the global warming that occurred some 50 million years ago.
No one is quite sure how it happened, but around 50 million years ago, the temperature of the planet sky rocketed. The shores of the Arctic ocean had palm trees lining it. Hippo's and Elephants lived in the Arctic circle. And perhaps most importantly to us, the number of primate species boomed, and eventually resulted 50 million years later in humans.
There are a number of theories as to why the planet warmed at that time. One is a meteorite that struck some high carbon content rocks. Another are some volcanoes that came up through other rocks that had a similar content. Another one is a methane burp, from the sea floor.
Whatever it was, the world warmed over the course in the matter of a few thousand years, and instant in geological time frame.
