Imagine women giving birth centuries ago or imagine you suffer from some critical injury or serious ailment. Centuries ago, there was not the concept of technology and there certainly weren’t the advances in medical science we have today. Your best option would be to call the tribal medicine doctor or shaman. Someone who knew how to use a leaf as a bandage and how to break and pull a teeth out with a stone.
Could you survive? Could you stay healthy? Could you even live long enough to see the next sunrise? Thinking of those types of situations now, it hardly seems possible, but we humans are tenacious and if it was impossible, then how did mankind make it this far? If modern medicines and advances in science are the only reason we are combating serious diseases now, then how did we make it this far?
