Cool New Forum Hadrian... LOLYeperoo Tiredness can be caused by many things...I believe your right.. Lack of sleep, LOL, over excercise, stress, improper nutrition lack of iron and other vitamins..certain illnesses etc.
I thought yawning was behavioural, from way back when we were all a bunch of apes, yawning was a way of synchronising everyone to sleep at the same time. probably lots of reasons why that would be a good idea. the fact that yawning is contagious is obviously the reason this works, but I really don't know why that is the case! I have read though that yawning does actually wake you up. It's used, subconciously, to give us a few more minutes of alertedness when we're really tired.

As I sit here Yawning and thinking of the power of suggestion I am trying to feel what is happening as I yawn,, My eyes begin to water and It feels great to take in those deep yawns in and release them..
I wonder if anyone else could really tell us..?
