my older sister forgot how to breathe when she was born... she was sucking on a bottle while my dad was holding her a few hours after she was born and she was turning purple. my dad had to take the bottle out and flick her foot to make her cry so shed breathe...... true story
Actually, I'm not so sure about that. You would faint first, but if you're able to breathe, you would breathe automatically so you'll prob. regain conciousness later. I won't go all biology on your ass, because I'll make a fool out of myself.
