From: Early-life exercise extends healthspan but not lifespan in mice

Early-life exercise exerts enduring long-term health benefits, improving healthspan, but not lifespan, in both male and female mice. Enhanced fatty acid metabolism in skeletal muscles is identified as a major feature in aged mice that underwent early-life exercise.
