50 years ago the american civil war was only 100 years ago (does that make sense?) Strangely the sixties doesn't seem that long ago for me personally. I wonder how the contemporaries of Kennedy thought about 1912, when there were few cars/planes, no radio, no television, no talking movies, no color polaroids, William Howard Taft was president and Europe/Russia/China/Japan was ruled by Emperors.
