Do you yawn when your not tired?

Yep... mainly in meetings
Lol

Yes, when someone else yawns. For reasons no one can explain, it's extremely contagious.

Lack of oxygen, it's the fastest way for our bodies to regulate that.

Yea, could be dehydration sometimes

Yea

kind of funny that you yawn when you're not tired AND you're called mushroomfairy. do I need to explain why that is funny ?

I do when I'm talking to someone I don't know or want to talk to - shows my disinterest. 😎

Yup, it's contagious.
