This must be the craziest idea yet coming from this iPhone. It is that yawning has an ancient purpose as part of the long life ritual!
First, most of us have not even heard of the long life ritual! Yet, this ritual can promote long life. It is something like yoga, but originates in groups in ancient Britain.
Second, it began as a response to early ancestors giving speaches and expecting everyone to sit hours and hours on end listening intentively.
Third, when you have the urge to clear your head and awaken, you yawn. The ancient long life ritual began as some one listening to old Lax go on and on about the importance of having a personal relationship with the invisible universal constant.
A young child in the audience yawned. Soon everyone was yawning like mad. It was so infectuous that old Lax himself yawned, and then yawned again, and then yawned again.
Well that's when the long life ritual began. Everyone yawned, and yawned, then fell asleep.
Well, you know that sleep is the long life ritual, but you must always begin it with a yawn. The more you yawn the longer your life will be. That is because you activate those passages to your brain that get clogged up during the day. A good session of yawning clears the airways and gets those hormones going that promote a good sleep and a great feeling of contentment.
