Love the idea but... 65% of oxygen? Do they mean oxygen or air? And shouldn't we contain at least a little bit of water? I guess the maker did do something wrong...
Twpk- Have you ever thought about from what elements water (H2O) is made up.....? So no- that list is correct on that part. The oxygen-part is correct and the Hydrogen-part is correct.
@twpk- this is a breakdown of *elements* in the body, not molecules (such as water) formed from billions (if not trillions) of different combinations of those elements.
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.

As already explained, individual elements and not compounds or chemical substances... of which water is one.
By 65% Oxygen and 10% Hydrogen, it puts you roughly in the ballpark of 60% water, which is what the average human contains. (Halve Hydrogen because two bond with oxygen to make water)
I doubted the numbers too based on the old we are mostly water idea. Post #10 had it right it is based on atomic elements not molecules. So we are mostly water which is two H for every O but every O has 8 protons and every H only has 1. So we are mostly O by atomic weight?

We should start to grow and harvest humans for all these minerals...!

Oxygen is heavier than hydrogen, and the ratio are in "percent of mass"
