I guess my thoughts on this thread are this: Is there any meat to the subject of the article? Maybe.
My thoughts as well. I think the nuance of a study versus action is lost on the article's author, as well. In 2016-2017-ish, they were taking extra blood from every helo pilot during their flight physical to fuel a study on vibration analysis of pilots*. I have no idea what happened with that study, and it wasn't meant as a way to act on anything specific, just collecting data. But I'm sure the media could have turned it into something much bigger if they got their hands on it.
* My joke was that I hoped I scored less than a .5 for forward flight. Ba-dum bump.
