It’s crazy how events of the past can affect us so deeply today. Like the plague or the holocaust. Millions of people died in each tragedy. Once a person dies, their possibility to reproduce dies, cutting off generations of people. like, the girl who sits next to you in math class never existed because her great-great-great grandfather was killed in the civil war. On an even more personal level, your wife, husband, best friend, neighbor, teacher, or favorite celebrity never existed because their ancestor perished on the titanic. This really just goes to show how lucky we are to be alive, we are truly one in a billion.
