Mitochondria and Aging

This interview portrays how aging has lately been linked to mitochondrial DNA (mtDNA) damage. Mitochondrial DNA provides energy to the cells; when damaged, they do not provide the energy they need to help you function properly and you get sick. Damaged mitochondrial DNA in genetic diseases is similar to damaged mitochondrial DNA seen in older humans, only the damage presents itself much sooner. Humans are programmed to overeat-to "store up for winter," but by overeating, mtDNA produces oxygen radicals that damage our bodies.
