I don't think I'd agree with their hypothesis though that there's no connection between dying in a random accident and fitness.

Fit people:

1. more able to "get out of the way" / coordination / agility

2. faster reaction time

3. potentially suffer a reduced injury

4. more likely to recover than die from the injury

There's probably a dozen rational things we could think of to counter that hypothesis.

5. more likely to be nearby certain types of random accidents

6. less likely to be nearby other types of random accidents

You’re making assumptions not in evidence. It’s well documented for instance that drunk people do better in accidents than sober people precisely because their reactions are slower and they don’t tense up.
