Ive fainted once ,Another close call the other day on the way to school aswell...But ill tell you what happed when I first fainted,When I yawn and stretch, I go all dizzy and walk as if ive been batty raped for a few sec's (Happens all the time when iam in this position)....But this time I yawned and strectched,Fainted,Fell backwards and my arse landed straight on the corner pointy bit of the table. Woke up around 15-20 sec's later just seeing my friend pointing and rofl-ing at me....I asked him why because I totally forgot what happend....
