So you ask for a citation, receive it, and ignore it. Color me surprised.
I ignored it because you provided nothing I can look at. It's the internet, provide a link.
Besides, I'm quite familiar with Dowd's shtick. He bases his analysis on life insurance actuarial data which contains no information about how sudden or unexpected a death was. Nor about thE see lifestyle of those who died.
It would be impossible to use that data to support your claim about athletes.
