Can We, and What If We Do?
Listen now
Abstract: For most of human history, what we today consider a "reasonable life span" was a significant achievement for the average human. This remains the case in many parts of the world, but for westerners in particular, the magic age "100" is becoming a milestone to which many now realistically aspire. Our science has allowed us to immortalize cells and is giving us pointers to achieving much longer life spans. Medicine and nutrition are also making rapid progress, and in many cases what were terminal diseases are becoming treatable inconveniences. But if being alive well beyond 100 years is possible, is it really "living"? What if we haven't planned to live that long; can we afford it? How will so many older citizens change our society? So, can we live beyond 100? The increasing numbers of centenarians affirm that the answer is "yes," but what are these special people made of and how can we learn from them?
