Have you ever noticed how on leaving a movie theatre you tend to yawn? Don't you ever wonder why? Most people I've asked why they do this answer: "Because of a lack of oxygen." I'm curious to know what you think.
For me I yawn when I go on my knees to pray. Do you? Why?
If you went to a casino you would probably yawn when you get to the parking lot, In casinos they pump oxygen into the air to keep you from getting tired so lack of oxygen doesn't apply here nor does being tired because if you left at 3 in the afternoon the same thing would happen.
I have my own theory but before I expound on it I would really like to hear what you believe is the reason for this strange phenomenon.
Here is something else that probably happened when you read the first word of this post......... Well did you or didn't you.
Sneeze......... No reaction.
Cough.......... No reaction.
