y where aging primarily takes place. In a car, we
know that aging takes place mainly in the engine, where gasoline is oxidized and burned. Likewise, genetic analysis
shows that aging is concentrated in the “engine” of the cell, the mitochondria, or the cell’s power plant. This has
allowed scientists to narrow the search for “age genes” and look for ways to accelerate the gene repair inside the
mitochondria to reverse the effects of aging.
