Why Do We Yawn?

You get up in the morning. You stretch your arms and there it is. Your mouth opens wide, you breathe in slowly and deeply, and then exhale quickly. You might even hear a rumbling sound in your ears. We call that a yawn. In fact, chances are that you just yawned right now because you were thinking about it. Babies do it. Adults do it. Even birds and mammals like our dogs and cats do it. We yawn when we wake up. We yawn when we need to go to bed. We yawn when we are bored.

Yawning is an involuntary reflex consisting of a wide mouth opening, a deep inhalation, and a short exhale. It typically lasts a few seconds and is common when you feel tired, bored, or waking up. It also happens when other people yawn. (https://en.wikipedia.org/wiki/Yawn)

But why do we yawn? There are several theories about why it happens. One idea says that the body is trying to get rid of excess carbon dioxide in our blood. Carbon dioxide is the stuff we breathe out. Another one saws that it is the body’s attempt to help keep us alert. It’s possible that the extra oxygen we breathe in can help wake us up. One researcher thought it might help cool the brain. For me, I notice is that my eyes get watery when I yawn. Maybe it helps us see better also.  Others think it could be a group signal to tell everyone it’s bedtime. One other theory says that it might help us keep our airway open and help us to be able to swallow and speak easier.

Did you know that yawns are thought to be “contagious”? Try it. If you are someone around you yawns, there’s a good chance that it will cause others to yawn also. Group yawn everybody! It could be that we are showing empathy (letting them know that we know how they feel). Some researchers have noted that some individuals that struggle with empathy also do not yawn along with other people as often. Although it has been used in movies by profilers to check for sociopathic, or psychopathic tendencies, there has not been a definite link established. This is still hotly debated since empathy is a difficult trait to measure. It might be that we just learn to imitate it when we were children. They say that our dogs learn to yawn from us!

Most of us cover our mouths when we yawn. Most likely this is because your parents said that is the polite thing to do. I mean, no one really wants to look down your throat! (We’ll maybe your doctor: and he tell you to say ah.) In the Middle Ages it was thought that you might “yawn out your spirit”, or that and evil spirit might get into you if your mouth was open too long, but we know that was just a myth. Still it’s probably better for everyone if you still cover your mouth when you yawn. Don’t want a fly to get in! Wow, I think I have yawned 5 times just writing this. Empathy? Or maybe I just need a nap…

What Would It Be Like to Live in a Castle?

 

In my blog for my grandkids, one of my grandsons wanted me to write about castles. His is going to be imaginary, with a diamond drawbridge, a lava mote and alligators in armor. It got me wondering what it would be like to live in a medieval castle. It is important to note that there is a difference between a castle and a palace. Castle were made primarily for defense, whereas a palace is a fancy living space for royalty.  

Medieval castles did not really come with a standard floor plan, but they do have many parts in
common. Across Europe there were 3 or 4 basic plans, but the surrounding terrain, water availability, and other environmental factors often dictated how they were designed.

The first thing you might notice is the wall around the castle, often called a curtain wall. It was normally made of stone. This wall could be up to two meters thick. It normally surrounded the whole castle. There would be openings high on the wall for windows. Many walls had the toilets built right into them. The waste would usually drop down into a moat. There were usually small, angled, openings in the wall called arrow slits or arrow loops where archers could fire at attackers without being out in the open. On the top of the wall was a parapet, a small wall about chest height where the archers could stand. Every few feet or so were higher sections called merlons, for soldiers to hide behind. There might even be openings called Machicolations that hang out away from the wall where soldiers could drop rocks or boiling oil onto an enemy. There were often towers built into the wall. They served as lookout areas, defensive structures, living quarters, and even prisons.

The only entrance in the wall was the main gate. It was guarded at all times and usually had huge wooden doors that could be barred from the inside. It usually included a gate of iron bars that could be raised and lowered. In most castles there was also a draw bridge that spanned the moat. It could be lifted to stop entry and also further help protect the gates.

The moat was usually a lake or deep pit that encircled the castle. It could be filled with water, or even oil that was lit on fire during a siege. The drawbridge was the only safe way across. Since the toilets emptied into it, it would not be pleasant trying to cross through it.

Inside the castle you would usually find a kitchen, a chapel, and a great hall which served as a banquet room. There could be stables and another fortified area called a keep. These were all housed in an area called the bailey, which was the hub of castle life and also contained shops and possible other living areas.

There was usually some source of water inside the castle. Since a river running under your castle wall could be a security risk, a spring or well would be preferable. If a river was the only option, there might be a secret tunnel to the river so water could be available during a siege.

Stairs in castles were almost always circular due to conservation of space. They always turned clockwise, which favored the defenders stopping soldiers coming up. Although the majority of the soldiers were right-handed, this design would be less of a hindrance to someone who fought left-handed.

As much as it would seem romantic to visit a medieval castle during their heyday, I imagine the smells would be alarming. Common people usually never bathed and the elite may have only bathed weekly. Couple that with the moat, and you realize that herbs, flowers, rose gardens weren’t just for looks. Still, I think they would be fun to visit and just imagine.

Short Beep or Long?

 I was paying attention, sort of. I was waiting at a light and already going through my upcoming day. And then I heard it. Beep! It was just a little beep. The kind that says, “I don’t wish to interrupt, but the light turned green. I like those kinds of beeps. They bring you back to reality, but don’t come across rude. It is also the beep that you to say ‘hi” or “over here”. I call it the short beep.

Then there’s the long beep. It says, ‘If your window was down and I was right beside you, I would be yelling in your window”. In text it would look like @#@#*!!*%@. Now don’t get me wrong, I have seen times where the long beep seems appropriate. But most of the time it’s delivered but mean people who just don’t care about being angry, rude, and obnoxious.

I myself am not a beeper. Not because I don’t want to, but because I seem to always forget which car I’m in. In my wife’s car, the horn is activated on the side of the steering wheel. In my car, it’s right in the center. To top it off, my car might honk, or it might not. Hey. It’s almost as old as my kids. When it does honk, it’s this embarrassing underwhelming “beep” that sound more like the Warner Brothers roadrunner than a car. Put me up against a truck and I’m gonna choose the better part of valor and just bow out.

So what does this have to do with real life? Well, if I have a choice, I’m going to use the short beep. Even if someone deserves a long beep, I want to be as gracious as possible. The bible says, "Let your speech always be gracious, seasoned with salt, so that you may know how you ought to answer each person." (Colossians 4:6) Romans 12:17-18 tells us, “Do not repay anyone evil for evil. Be careful to do what is right in the eyes of everyone. If it is possible, as far as it depends on you, live at peace with everyone”. I’m sure there are time that most people agree that a long beep would be fitting. I strive to give the person a little slack. You have no idea what they have just been through. Perhaps they just got bad news about a job or a project they were working on. Maybe they, or a loved one are going through a tough medical issue. I personally want choose to give them the benefit of the doubt. So what will you choose? Short beep or long?
