Why am I resistant to the covid virus?

Both of my mom and dad have been coughing since they came back from Europe on October the 5th and I have not coughed even once.

I think there are two possibilities: One is that I have a gigantic head cause I read high I. Q. people are resistant to the virus, another possibility is that I eat 12 slices of cheese every day because I need the fat in cheese to process the minerals and vitamins I eat to lose weight. I read even moderate amounts of cheese decrease your chances of getting covid by almost 40% so high amounts of cheese might decrease your chances by 80% or 99%.

A third possible reason is that I've always had very very very thick bones. All my life. I don't mean body fat cause I was a normal sized kid, I mean my bones are big and strong and large.
