Yawning is not a disease.
if rude and yawning are defined as such i don't see any reason why the act of yawning be rude. yawning is physiologic. would urinating and defecating be rude also?
The cause in not know.
Yawning too much can prove to be fatal. My aunt didn't sleep for a week, kept yawning, and died. You're in trouble
Breath smells bad becuase people are not very smart and do not have proper dental hygene. so basically you don't brush your teeth.
Yawning is actually putting out (?) the stress in your body, so it is a good thang...
Yawning is associated with tiredness, stress, overwork, lack of stimulation, or boredom. Yawning can also be a powerful non-verbal message with several possible meanings, depending on the circumstances. In humans, yawning has an infectious quality, i.e. seeing a person yawning, or just thinking of yawning, can trigger yawning which is a typical example of positive feedback. Infectious yawning has also been noted in chimpanzees. The primary reason behind yawning is to control brain temperature. It cools off your brain, much like a fan cools off the inside of a computer. The claim that yawning is caused by lack of oxygen has not been substantiated scientifically. Some claim that yawning is not caused by lack of oxygen, for the reason that yawning allegedly reduces oxygen intake compared to normal respiration. Another speculated reason for yawning is nervousness and is also claimed to help increase the state of alertness of a person-paratroopers have been noted to yawn in the moments before they exit the aircraft.
it isn't, yawning is due to the fact you are breathing slower and not taking in enough oxygen
"I'm yawning. I'm yawning some more."
The Yawning - 2012 was released on: USA: 14 December 2012
Some studies say that yawning occurs when your brain is overheated. Maybe your hearing decreases because of this heat? Yawning is still a mystery.
