It's very likely that aging is driven by some kind of scheduled gene program. It makes perfect sense to phase out individuals from a group-level selection point of view.
I feel 25 years younger now. My BP and cholesterol are under control and I roll out of bed actually feeling rested (probably due to not snoring anymore).

Maybe. But why in this case do we not see bugs and failures in this program, i.e. no one lived 5 times more than the average or did not live forever at all, for example? I'm not making a statement, just a guess.

But that's just guessing. The article might not even have found something profound, but a life-style effect. On the one hand, we're living long (historically speaking), on the other hand, we have unnatural habits.
I felt incredibly old from ~36 - 42. Then I started seriously working out, took control of my diet (it had very much always controlled me) and started aggressively pursuing a "better living through chemistry" approach to life. I feel 25 years younger now. My BP and cholesterol are under control and I roll out of bed actually feeling rested (probably due to not snoring anymore).

It's the same as how although you can occasionally get a "natural" person over seven feet tall, it's very rare. Most really tall people have gigantism or some other form of pituitary abnormality, and I believe every recorded person to break eight feet has had such an abnormality.
It's like asking why we've never had someone with 500 IQ. There's a hard limit where anyone with enough of a mutation to enable that would probably also not survive long at all. And indeed with the height thing we see a lot of super-tall people dying younger due to cardiovascular strain and other issues. You get the picture.

Is there convincing evidence for group-level selection in evolution at all? I read enough Dawkins back in the day to be skeptical of such claims.

Because the odds of something 5x the average that's more or less normally distributed are really, really low.
