People with mtDNA levels in the bottom one-fifth of the population were 47% more likely to die of any cause than were those in the top one-fifth. Interestingly, women had an average of 21% more mtDNA than men and could play a small role in why women live two to four years longer than men on average.

Some new research indicates that stem cells are actually able to replace damaged mitochondria in other cells.
