From Free Will Astrology:

“Quoting leading geneticists, writer Guy Murchie says we’re all family. You have at least a million relatives as close as tenth cousin, and no one on Earth is any farther removed than your 50th cousin. Murchie also describes our kinship through an analysis of how deeply we share the air. With each breath, you take into your body 10 sextillion atoms, and–owing to the wind’s ceaseless circulation–over a year’s time you have intimate relations with oxygen molecules exhaled by every person alive, as well as by everyone who ever lived. At this moment, you may be carrying atoms that were once inside the lungs of Malcolm X, Janis Joplin, Christopher Columbus, Joan of Arc, and Cleopatra.”
