Human history has been all but defined by death and disease, plague and pandemic. Advancements in 20th century medicine changed all of that. Now advancements in 21st century medicine promise to go even further. Could we bring about an end to disease? Reverse aging? Give hearing to the deaf and sight to the blind? The answer may be yes. And soon.
