> I wonder if the extended sedentary lifestyle imposed by the lockdowns is also to blame to some degree. During the lockdowns I was less sedentary than before, since I had more time to take long daily walks and I also did a ton of physical work building a house with the time saved from commuting. Still, after I finally got COVID a few months ago, I've felt more fatigued than normal months after testing negative. Walking up the stairs suddenly got more tiring more often.
