breathing puts more oxygen in the system than anything else. dude, meth is a hell of a drug, get off it.
but the air cant get in if the blood is too thick, too high blood pressure ect...thus the demand for oxygen can increase during workout but cant get in because of this factor causing potental clotting and heart attack
water is a cooling agent, natural blood thinner, and diuretic
btw anyone notice how my avatar has a mind of its own? check the eyes on this post and then look at my previous posts, two different eye expressions, on this post it seems to be a much more sinister expression!

but now it turned back to normal wtf
