This concept, first proposed in 19721445 and known today as the mitochondrial theory of aging, suggests that, over time, free radical damage to our mitochondria leads to a loss of cellular function and energy. Our mitochondria are the power source for our cells. Think about charging your phone over and over; its capacity diminishes every time you recharge it. Similarly, as our power plant mitochondria accumulate free radical damage, they may also lose function over time.
