The body is made of organs that are all constantly working with and for each other. If it weren't for the synergistic compatibility of these organs then the body would not be able to function properly.

Though, the complexity of body extends much deeper beyond the organs beneath the skin. Each of these organs is going to require nutrients just like you do; in fact, in exactly the same way you do because they compose you.

Among these nutrients the body needs oxygen and water. Water is easily transferred throughout the body being carried by vacuoles in the cells, but oxygen is a little trickier to get a hold of.

To transfer oxygen throughout the body you need to have a little substance called hemoglobin. It sounds like the goblin cousin of Bilbo Baggins, but it is actually the oxygen carrying pigment in the red blood cells.

Hemoglobin is made of metal, iron to be more specific. But, the body doesn't just take iron and bend it into hemoglobin.

It actually has to go through something very similar to a smelting process. You need to have copper and iron boiled down and stirred together then passed through to the blood, so that the endoplasmic reticulum and Golgi apparatus can fashion the hemoglobin in the red blood cells.

Sounds like something from skyrim, but it is actually completely real and skyrim is just a videogame that provides no real sustenance, but is still fun nonetheless. The cells in the body are each like small communities, and you are like a gigantic universe that houses anywhere from 50 trillion to 100 trillion little communities (communities is a euphemism for cells.)

Oxygen is a necessary component in energy, without it you wouldn't even be able to use your muscles. Many people deter their muscular development because they do not have the proper cardio strength to feed their muscles oxygen during their exercise.

Along with cardio strength you also need to have the proper nutrients to feed the cells and provide the ability to use the oxygen correctly. If there is a deficiency of either copper or iron in the body then you will be prone to acquiring anemia.

In laymen's terms that means you are going to feel lazy all the time. That is not actually the dictionary definition but the consequence and side effects of having anemia.

Protect yourself from pointless lethargy and also thin blood (which is another side effect of anemia), and start eating metals, not like pennies or anything, everyone knows those don't provide an ounce of nutritional value, in fact with this inflation it is questionable whether they have any value at all. Buzzing!
