A really good immune system. I get a cold maybe once every two years and they only last for about three days. I also don't get fevers (nobody knows why), which I know is kinda paradoxical but my immune system somehow is really good at dealing with infections despite this.
Same. My partner calls me a fortress. She is frequently coming down with colds, like once a year at least. And covid twice. Meanwhile, I haven't got noticeably sick since the first lockdowns.
Hope that doesn't just mean I'm contagious af. I keep testing negative on the RATs anyway
