A dose of common sense via the Life Extension Foundation News: "The life span of human beings is partially influenced by genetic factors, but outcomes of aging are profoundly influenced by lifestyle and other environmental factors. Age-related modifications of the cardiovascular system are preserved by anti-aging lifestyle interventions such as physical activity and caloric restriction. ... Accordingly, physical activity and low body mass index reduce mortality in older men with cardiovascular diseases. ... Thus, older persons can implement lifestyle practices that minimize their risk of death from cardiovascular diseases." It works over the long term for younger people too: you can choose not to damage your healthy life span, and thus have a better chance of living to benefit from real anti-aging technologies of the future.
