The average human has approximately 100 trillion cells and each cell is made of approximately 100 trillion atoms, each of which were originally created in the center of a star. The atoms that are in your hands may have been created in a different star than the atoms in your feet, so by definition, we are galactic beings because the very structures that make up our bodies come from across the galaxy...

The Human body is made up of four main ingredients, Oxegen, Carbon, Hydrogen and Nitrogen. This image breaks down what the body is made of and makes most interesting reading. Plus, looks kinda cool lol.

Seems right!

And greys have a lot of silicons ~('w')~
