Smiles

Smiles seem to be...baked into us. Babies smile almost as soon as they're born...some smart guys in white lab coats, even claim babies smile BEFORE they're born. Those same smart guys say smiling lowers your heart rate so it will keep ticking longer.
Actually I have a...contrarian...experience to that one...the first time my Lady Wonder Wench smiled at me, my heart rate went through the roof. But of course there are exceptions to every rule.
Blind people smile even if they were blind at birth, so they've never seen a smile. I swear I've seen dogs and cats smile. Different animals have different ways of saying "Hey I'm happy." Ducks and I guess most birds can't smile, because they have those solid beaks. So ducks and most birds shake their tails when they're happy. I've seen some pretty ladies do that too when they're happy. Very nice.
We're learning more and more about animals. A couple of weeks ago, I saw an article that said cows have friends. Probably farmers with warm hands. Speaking of cows, I saw a stat that is kind of hard to believe about people and cows. It said 7% of American adults believe chocolate milk comes from brown cows. Those people should not be left un-attended. Lots more about smiles in this podcast. Give a listen please.
