Every human needs oxygen to live, every one knows that. Have you ever thought what would be like if humans didn't need oxygen to live and they just didn't breath. We would be able to go under water and stay down there for as long as we want!! Or if there was only a few people who had that ability ( to be able to not breath) they could have contests with people ,who didn't have that ability, and win. Well I guess we can only dream about things like that!!Oh! I can't breath!
