Support For Reliability Theory

Fight Aging!

Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging. The sooner these treatments arrive, the more lives will be saved. Find out how to help »

A study reported at EurekAlert gives the expected support for the reliability theory of aging: "Records from four European countries show that, on average, survivors of generations with rampant childhood infection - measured by cohort mortality rates at young ages - were shorter and died sooner than counterparts from generations with less childhood disease. Crimmins and Finch propose that even when they grew into apparently healthy adults, survivors of high-infection generations carried a heavier lifetime burden of inflammation. This in turn accelerated the progress of cardiovascular disease. ... Our model implies that the reduction in lifelong levels of infections and inflammation reduced and delayed the progression of cardiovascular disease and mortality due to heart disease."
