hmmm... I am not sure if I believe this t-shirt. If the human body is supposed to be around 60%-55% water and for every one part oxygen there are two parts hydrogen, does 10% hydrogen add up? Also most organic molecules contain hydrogen, there is generally a greater ratio of hydrogens than carbons in the general amino acid structure, and amino acids are the building blocks for all proteins. Certainly the mass of hydrogen is far less than oxygen or carbon. Is that what the t-shirt means, is it the percent of molecules by weight and not representative of the relative number of molecules? Is this a wet weight or a dry weight calculation? Would a dry weight measurement really be representative of a living being? Does this calculation include air in the lungs, or is it just tissue? How does one go about making these measurements, is it from tissue samples of the dead or the living? I am confused, so many unanswered questions.
