I just managed to read the Medscape article. Pretty useless, in my view.
But Kati in the comments (I think that's the same person as
@Kati on these forums?) posted good comments. So maybe that will help sway some folks reading the article who are unsure. She even got a response from the editor about the error in the title (saying Exercise instead of Exertion). So that was nice!
However, if the "exercise" instead of "exertion" was only a headline error, then why did the author also make the same mistake in the body of the article? I did not view the video so I don't know whether the author also said the wrong word or whether it was a spell check or editorial correction.
At any rate, I don't think the article provides any useful information at all for folks on this forum. Just my two cents.
