Bored?

Only boring people get bored! I have always liked that saying,now if I can segue into today's topic without further ado...Yawning is one of those simple things we all do but one that scientists don't have an explanation for. The first explanation I remember hearing was that your body would induce you to yawn if you had an oxygen debt,and you would get the needed oxygen by yawning. They do know it's involuntary action because even fetuses yawn as do most inverebrates. Another theory is that yawning acts like a fan for the brain,when it becomes too warm we yawn to cool the brain down. By now you may be wondering how either of these explanations fit with contagious yawning and neither really do. The empathic yawn is your neurons causing you to feel what the yawning person feels and perform the same action. Before I wrap up for the day I wanted to touch on boredom again. There are studies being conducted that indicate boredom may have health consequences,depression,overeating,substance abuse,gambling and indirectly people can be "bored to death". So with that said,quit yawning and keep it entertaining!
