I really want to call bullshit on this but am willing to wait quite a long time to see scientific studies. I mean sadly the research is going to take YEARS to fully understand. The scare-tactic style writing in some of these articles is really brutal.
I mean what do you ask people?
- Do you ever feel tired? f*** yes I feel tired. Every day!
- Do you have trouble breathing when walking up stairs? Oh give me a break...
- Do you sometimes have a dry cough? "YES!"
Obviously I'm exaggerating a bit, but I see this in fitness studies all the time. When we finally break down and look into the study, the data set, etc... you would be shocked at how much bullshit is in research. That being said - I would remain completely neutral on this topic until years go by and we get multiple different studies. From the people I know that had it, absolutely none of them have any symptoms. What I would expect is at least a few of them to say "I still can't get to that high level in fitness." Even some of the elderly people who aren't active that got it and survived aren't experiencing anything out of the norm.
Like I said this will definitely be an interesting thing to watch as years go on.
