Interestingly, it seems to be affecting younger people.
In Turkey (where I got that 20% figure from), only 2 people out of the 20 cases there were older than 18.
Some are saying it's because the kids are more likely to be playing in the chicken coops, or interacting with the chickens, or they're less sanitary.
Others say it might favor them for some reason or another. We really wouldn't know unless a pandemic actually happened.
Someone freepmailed me asking about the recent study on elderberries and bird flu. Here's a link in case anyon else is interested:

BTW, I admire your politeness in the face of rudeness.
