. . . . (Because muscle cells require so much energy, they’re hit hard when mitochondria go down.) Some researchers now see aging itself as a kind of mitochondrial disease. Defective mitochondria appear as we get older, and these researchers say that they rob us of endurance, strength and function. There’s evidence that for young patients with mitochondrial disease, exercise is a potent tool, slowing the symptoms. If that’s true, then exercise could also potentially be a kind of elixir of youth, combating the ravages of aging far more than we thought.
. . . .
You don’t have to be an athlete to notice how ruthlessly age hunts and how programmed the toll seems to be. We start losing wind in our 40s and muscle tone in our 50s. Things go downhill slowly until around age 75, when something alarming tends to happen.
. . . .
EXERCISE HAS BEEN shown to add between six and seven years to a life span (and improve the quality of life in countless ways). Any doctor who didn’t recommend exercise would be immediately suspect. But for most seniors, that prescription is likely to be something like a daily walk or Aquafit. . . . .
Exercise (and diet) is important to good health, especially later in life.

Just ran across this. Wow. I tell everyone that I am going to live to 150 :wink: and people like this give me encouragement.

she won't live forever, but at least she has a chance of dying healthy.
 
In a muscle sample of a person over the age of 65, you would expect to see at least a couple of fibers with some mitochondrial defects. But in around 400 muscle fibers examined, Taivassalo said, “we didn’t see a single fiber that had any evidence” of mitochondrial decay. “It’s remarkable,” she added.
