Debate Details

The Future Of The GOP

What if we didn’t have to grow old and die? The average American can expect to live for 78.8 years, an improvement over the days before clean water and vaccines, when life expectancy was closer to 50, but still not long enough for most of us. So researchers around the world have been working on arresting the process of aging through biotechnology and finding cures to diseases like Alzheimer’s and cancer. What are the ethical and social consequences of radically increasing lifespans? Should we accept a “natural” end, or should we find a cure to aging?

What Happens When We All Live to 100?

On Dying After Your Time

Daniel Callahan
November 30, 2013

We may properly hope that scientific advances help ensure, with ever greater reliability, that young people manage to become old people. We are not, however, obliged to help the old become indefinitely older. Indeed, our duty may be just the reverse: to let death have its day.
