Life is crazy. From the complexity of the human body and the intricacies of our brain to the way we react with one another and the sociological phenomena of living in large, dynamic societies our lives are something of a beautiful mess. As humans we are simultaneously some of the most complex, tough, simple, and fragile things in the universe. Whether it is an unbelievable fact about our physiology or something interesting about the way we relate to one another there is sure to be something on this list that you didn’t know. For example, did you know that nearly 2/3 of the people in the history of humanity that lived to be 65 years old are alive today? While that sounds crazy it is primarily because more people are alive today than ever before. In fact, out of the 108 billion humans estimated to have walked the Earth, more than 7 billion of them are alive today. That means that only 93% of humans in history have died! Isn’t that mind boggling? Out of all of history, 7% of humans are alive today. Our world has changed so much and this list will pay tribute to that fact.
