Yeah, I've read some articles.I think scientists are looking to study people like you guys....to see why some people seem to have more natural immunity. I was hoping that I was going to be one of the special ones....but then saw the dreaded second line and realized I'm with the rest of the herd. Oh well.
I think we are just naturally immune to majority of illnesses. We don't do anything special mind you, it just is the way it is. The way we are.
We rarely get the flu or colds.
I've been at my employer for close to 30 years and other than a case of diverticulitis have had only 1 other illness absence in all my employment time.
DH isn't quite as lucky as I am but close.
DD and DGD are both like me. DD went her entire childhood avoiding being sick. As a single parent most of that time I was ever grateful too.
Anyway, I'm not sure we are the best candidates to study since our ability to avoid illness extends well beyond Covid.
