mitochondrial theory of aging

The mitochondrial theory of aging suggests that the decline in cellular function over time is largely due to damage in the mitochondria, the energy-producing structures within our cells. As we age, mitochondria accumulate genetic mutations and suffer oxidative stress, leading to decreased energy production and increased cell damage. This impacts overall health and contributes to the aging process, resulting in diminished physical function, increased susceptibility to diseases, and overall age-related decline. Essentially, maintaining healthy mitochondria is considered vital for longevity and vitality in aging.
