Gold is present in low levels throughout the Earth. It’s been found on every continent except Antarctica, as well as in the planet’s core, the oceans, plants, and humans, too. The average human body of about 150 pounds is said to contain about .2 milligrams of gold, which we excrete through our skin and hair. Babies less than 3 months old tend to have more gold in their manes than older people, thanks to the precious metal being passed along in human breast milk. And while no one’s suggesting we should mine the gold in hair or breast milk (as far as we know), researchers are studying whether gold — and other metals — might be recovered from human waste.
