I was trying to figure out what yawning could possibly do for us and the 
answers everyone has come up with didn't make sense to me....and i kept 
yawning while reading these questions(try not to) and i noticed that it felt 
kind of good....like when your stretch your muscles...maybe it gets the blood 
flowing in muscles that don't get used all to often......i'm not sure if there 
is muscles in our heads, but i notice when i yawn it feels like i'm streching 
muscles in the back of my neck........?
