Some people understand the potential for technological advances to foster real social and personal change. Among them is Michael Zey, whose groundbreaking predictions about superlongevity — humans living up to 150 years — are detailed in Ageless Nation. Designer children, nanotechnology, and other advances, point the way toward a future where the aged live healthy and happy lives usually enjoyed by those decades younger. Zey focuses on the social effects of superlongevity — with regard to careers, business, marriage, and children — and how these shifts in daily life will ultimately be for the better.
