that theory doesn't seem to encompass all that is know.

> Wallace notes: “The mitochondrial theory of aging holds that as we live and produce ATP, our mitochondria generate oxygen free radicals that inexorably attack our mitochondria and mutate our mitochondrial DNA.”1

if aging is killing the mitochondria, why then the mother passing mitochondria to the offspring give them a blank state if they got dna-damaged mitochondria to begin with?

The mitochondria that mothers pass down are from a special group of cells that already existed when the mother was born and they are kept in a special, protected state that minimizes damage.

Wouldn't they still degrade every generation? I'd expect them to be created new, like new spermatozoa that are born with long telomeres.

If that was true then how would any other single celled organism be able to exist?

Plot twist: Earth life is slowly running out of mitochondria.

Could you please expand your comment for people, like me, who doesn't have a good knowledge of medicine and/or biology?

Also, are you saying that LLLT fails on its claims? If so, could you please reference some study to follow the topic.
