#2Hasn't this been known for a while now? I swear I learned about this in AP Bio a decade ago.

#3For humans, about 15 kbp telomere can be reduced to 50% in about 107 years at the rate of about 70 bp per year. That number goes well with the max life spans we observe in humans.

You probably learned about the telomere length, not the shortening rate.

#5The total number of heartbeats also predicts lifespan, although apparently not as accurately. So is the heartbeat total just a coincident or still a factor somehow?

The graphs on Fig. S2 doesn't seem to map well to the points. I would say these 2 are not related. To me, the mouse looks like the outlier.

I've seen this before and get the gist, but at face value, it's ridiculous. A human who runs every day may expend twice the heartbeats of a sedentary person. He or she will not live half as long, or anything close to it.

I think the idea is that a frequent runner will have a much lower resting pulse rate, and the “extra” beats they use while exercising will be more than offset by the fewer beats that accumulate during rest?
I haven’t done the math though.
