The quote below was taken from a Washington Post article passed along today by a friend. The article's idea of living longer or outwitting death was titillating, but there was something superficial about it, as if the problem might be agreed upon without really investigating why or how it might be a problem. But that was just my take.
The quote that caught my eye was this:
No one seems able to predict what life might be like when half a dozen or more generations are alive simultaneously.
