Yaaaaaaaawn!

Chasmology! The study of yawning! It’s a real thing! There’s even an international conference!

Everybody yawns!

yawn1_03

Even human fetuses!

Seeing, reading, or thinking about yawning triggers more yawning in humans (except those of us with schizotypal personality traits). Contagious yawning happens more often when you’re warm and when you breathe through your mouth and most probably is a primal, uncontrollable expression of human empathy.

So it’s no surprise that children don’t yawn contagiously until they’re a few years old.

If you’re out with your Romeo or Juliette and they start to yawn, don’t fret! In people, yawning is triggered by some sex-related agents like oxytocin and androgen, and many males get sexually aroused when they yawn.

And one more thing, to set the record straight: Research shows we DO yawn when we’re bored, we DO yawn because we’re sleepy, and we do NOT yawn because of high CO2 levels or low O2 levels in the blood and brain.

Holiday Reruns: Five Conversation Starters for the Thanksgiving Table

Tongue-tied with Uncle Tommy? Sick of Aunt Sally’s prattle? Try some of these BHR-approved conversation starters to get things going this Thanksgiving.

1. “My little heart goes pitter pat just being surrounded by all of you loved ones. Speaking of hearts, did you know smaller animals’ hearts beat faster than larger animals? Well, they do.

2. “It sounds like that investment banking career is really taking off for you, Mike. Oh, me? I just took up omphaloskepsis.”

3. “No, I’m not being creepy about your baby, Janet. I’m expressing a natural evolutionary urge to protect him.”squeezeit_05_03
4. “Oh, look at the moon! It’ll look even smaller tomorrow night. How do I know? I just know.”

5. “It’s natural to share, Jerry. But you gotta work for it. So no, you’re not getting any of my pecan pie.”

We Got the Beat

Metabolism! The stuff our body does to keep us rolling down the road! Powered by our hearts!

beats_record

Print

Some scientists say all animals have a fixed number of heart beats before we die (955,787,040, to be exact).

dancedance_mouse

 

While not always true, metabolism (and heart rate) generally correlates with lifespan. Animals with slow beats live longer. Be still, our hearts—or at least slow down!

Vocabulary Friday: Omphaloskepsis

Omphaloskepsis is the act of contemplating one’s own navel.

1_surfgirl_fade

We should all do it!

2b_beachall2_long_why

 

Because our belly buttons are packed with life! With an average of 67 different types of bacteria living in each one of our belly buttons, each one of us has a unique microbial fingerprint.

That’s omphaloskepsis for you. Time to look on down and start omphaloskepsisizing (not a real word) about the personal jungle you carry with you.

We’re Going to Squeeze It

According to Neal Singer’s awesome book “The Wonders of Nuclear Fusion,”

squeezeit_01

That’s what we thought was happening inside us when we saw baby otters…

…or animal best friends…

. . . or anything to do with red pandas or sloths.

Then we found out that, whether from a need to protect or happy overload, cuteness arouses aggressive responses in people.

Get Moving! How to Navigate the Great Migrate.

Ancient civilizations couldn’t figure out how animals came and went with the seasons. They came up with all kinds of stories

rsa_migration1_01

But the truth behind navigation turned out to be way better than anything they could have imagined. Bobolinks take an annual trip of more than 12,000 miles. Monarch butterflies bat their wings for up to 6,000 miles.

rsa_migration2_01

With no GPS, how are they doing it? Lots of animals get their major move on using these three tools:

1. Sun compass

rsa_migration4a_01rsa_migration4b_01_01

2. Stars. Most migrating songbirds travel by night. They learn constellation patterns and orient to those patterns. Light pollution throws a monkey wrench in their plans.

rsa_migration3_01

3. Magnetic fields.
