Mitochondrial dysfunction, specifically through ROS generation, mtDNA mutations, and altered redox homeostasis, is a primary driver of the aging process.
Focus on interventions that support mitochondrial health, such as exercise and dietary restriction, as these organelles are central to aging mechanisms. While specific protocols aren't detailed here, the paper highlights that boosting mitochondrial function (e.g., via exercise) can decrease markers of age-related diseases like Alzheimer's.

The more we learn about mitochondria, the more fascinating they become and the more they seem to be implicated in aging... Presently, new theories have been put forward suggesting a role for mitochondria in aging which is independent of the generation of ROS. For example, it has been proposed that aging is caused by the accumulation of mutations and large-scale deletions in mitochondrial DNA (mtDNA)... It has also been proposed that aging can be caused by an alteration of the redox homeostasis, since mitochondria regulate the relative levels of NADH/NAD+, NADPH/NADP+, and GSH/GSSG.
