I am such a “at least one cup a day” coffee drinker, and did not get hit with the Covid-bug, though being in the L.A. and then NYC areas when it started, and traveling multiple times coast to coast between Dec 2019 and early 2021.
But I suspect there is some other variable that regular coffee drinkers frequently (not always) have in common, and that variable was not considered in the study. I think they found a correlation but not sure they found a cause.
I smoke cigarettes with my coffee. That might be it.
“I smoke cigarettes with my coffee. That might be it.”
Maybe my longs have “residual protection” from smoking for many years though I also quit about 40 years ago. LOL
