    Yes, all dogs and cats yawn, too; even in their sleep, or when awake. I read an article (this week) in the Smithsonian Magazine and it was very interesting to me on yawning.

    Scientist wondered too, and noticed test subjects brains became "cooler" when they yawned--even in their sleep! So they are coming to the conclusion that it does indeed cool our brains, and we don't do it just because others do it; they are cooling their brains as well and that is WHY they do it!

    I love little know things like this!

    So, if I say, God is marvelous it fits the R&S section!

    Some do yawn, some do not. From your profile:

    "I converse with all" yet you do not allow email contact.

    &

    "I prefer sources to be given (or quotes) not just opinion." Yet you did not include either sources or quotes.

    Josiah question.
