1. Death isn’t preventable. We will all die, so if you prevent one cause of death in old age, you will just die of another cause of death. Sure it might extend your life a little bit, but I feel it’s entirely rational to seek out information on causes of immediate death as more relevant than causes of long term death. The probability of living much older than 100 is virtually nil. Probably good to have information on both though.
2. It’s possible they are major causes of early death, but I can’t figure that out from the article and it would be nice if the article provided that information.
Although we should remember that “old age” is long. Someone can die at 72 from heart disease and people might just call that dying of old age when that person could have easily lived another decade or two if they made different lifestyle choices. That would be more of an “early death” than a centenarian dying in a car accident. The suddenness is irrelevant.

I can tell you're quite young :-)
Old age is pretty broad, and you really need to start worrying at some point in your 40s. Although death due to these is rare at that age, you'll likely end up knowing 1-3 people who will die of these at that age. And a lot more in the 50s.
There's a huge difference between dying in your 60s (perhaps right before retirement), and dying in your 80s. Lumping all of these people into "old age" is likely a byproduct of the same biases that cause journalism to not report on it.
