I'm shocked. Shocked that someone could get it all so wrong. For the body to do what you say it does would throw the ideal gas law and Le Chateliers (sp?) principle out on to the street. Thats not even counting all the centuries of acculmulated biological evidence and knowledge. I mean, you can SEE the heart beating and pumping with certain imaging modalities - you can even see it during thoracic surgery.
I'm just sitting here gobsmacked. I don't know what else to say. Good luck with.. everything I suppose - I think that you're gonna need it...
