Hello
Yawning is an involuntary opening of the mouth wide, and taking a deep breath. Often it is due to boredom. Watch everyone else yawn when you yawn! Good luck
Hello,
It is not only out of boredom, you will also yawn when you feel sleepy. On the whole, it happens when your body is lacking enough oxygen, take care.
