How Long Can Humans Live?
Given the remarkable scientific and medical strides in the past few decades, many of us now wonder: “How long can humans live?” Of course, that brings up the difficult issues that society needs to deal with: How long should humans live? In other words, what are the complicated ethical challenges brought about by extending lifespans? Babies born this year have a life expectancy of 80 years, but just half a century ago that number was 72, and a full century ago it was just 50!
How will longevity change society? Should we be considering age-based limits on some activities (i.e., driving, mandatory retirement)? What medical choices should be available to various individuals in different circumstances, and are federal laws required in some areas? These questions have legal, moral, and ethical consequences.
