As the treatment of aging as a medical condition became more mainstream, there was a tendency for advocates and researchers to avoid talking about extending life span. They instead talked about pushing back the onset of poor health and even said explicitly that the goal of research and development was not to lengthen overall human life. From the perspective of aging as an accumulation of cell and tissue damage and potential rejuvenation therapies as repair of that damage, this view is incoherent. A priori, we know that repairing damage will extend both the overall life span and the period of good function in machinery, including biology. This is well studied under the heading of reliability theory, modeling how damaged systems fail. In medicine, however, we […]
