If I Live to Be a Hundred

The very old fascinate. Their astounding longevity amazes and makes us think what it might be like to live another 50 or 60 years or yet even longer. Personally, I can't imagine life 60 years from now. Will blindness be cured? Will blind people have it better or not? Will technology make things better for all of us? Will slavery be ended everywhere? Will nano-technology be commonplace? Will the U.S. still be the world's most powerful nation? What about China? Will alternative medicine be so alternative? Will we have a trillionaire? Will the asteroids be mined for iron or platinum?
