We moderns take for granted many traits that were those of gods. Like
flying through the air. We fill dark rooms with sudden lavish light,
with the twitch of a finger. Average folks send messages or observe
events across the globe through crystal tubes we command like genies.
And yet the one trait of mortality that clings to us is...mortality.
Today, a fresh crop of true believers, including brilliant scientists,
view death itself as a problem to be solved. Are they fantasizing? What
are the prospects and problems and unforeseen side effects of longer
life spans?
