That article really isn't science, it wouldn't resemble science on a dark foggy night from a distance after you'd had a couple of drinks. "Feel the Qi" is not a scientific journal, the same comparison applies. It is in fact the worst sort of psuedoscientific pap, the text is meaningless, yet attempts to sound scientific, like a shampoo commercial. The nearest it comes to actually citing an article is mentioning that "someone" in 1896 said something vague about muscular activity and breath. If a science student at university handed that paper in not only would he fail but he would probably end up being escorted from the premises by security and given a good kicking on the way out.
