V2人们都想extend the human life span，可是这样会浪费资源，降低每个人的生活质量 What if , by the end of this century, we could more than double average life-span to between 160 and 180? Given that possibility, these are the issues that should be thoroughly discussed and debated. At some point, the number of people may become sa large that it exceeds the carrying capacity of the planet, making life miserable for the vast majority of humans (and impossible for other species), even sowing the seeds for our own destruction. The quality of life for very old people may be severely diminished, if changing the boundaries of aging is not accompanied by reasonable health. Certain tissues and organs may deteriorate even as life-span is markedly prolonged, so people may live 140 years with ever –worsening sight, hearing, mental function, and musculoskeletal function. Meanwhile, we might be expected to work, support ourselves, and pay taxes until age 80, 90, 110 or older. Some of us will outlive our resources and spend our extended years live in poverty. This would likely create intense adversarial relations between younger and older persons as they compete for limited jobs and resources. -- by 会员 熟睡的水 (2011/6/18 0:39:27)
