For me personally, in the before times, getting sick a few times a year was just a fact of life. Nothing anyone could do about it. For me, it felt particularly bad. I am not the type of person who recovers quickly. Things that take my DH a few days to get over takes me 3 weeks. Getting sick ruined activities, I felt like I was perpetually recovering from something after traveling. And then when the COVID mitigations started... I haven't been sick once. I don't think that will last forever, but what it has taught me is that getting sick is not inevitable. I had seen Asian people mask while traveling or doing errands while we were in Hong Kong and Tokyo and wondered if it was really doing something. After this, I am open to the possibility that it might. I don't want to go back to that part of 2019 and before. If I'm sick, I don't want to feel obligated to participate in situations where I can make other people sick because it's expected to just "power through." If I can do things that do not feel inconvenient to me, like wearing a mask while traveling so that I don't get sick on vacation, that's a good thing. So I feel more aware of the situations in which I can get sick or contribute to making other people sick. Not just COVID, but anything and I don't really want to do that anymore. Like instead of dieting, make lifestyle changes... as far as sickness in general, we are willing to make lifestyle changes. Not sacrifices, just changes.
