Totally anecdotally, the 4 people in my family who got it are all 65+ with multiple underlying issues. It was a bad head cold for a week and half, all recovered. I know, sadly, that isn't the case for so many. I just don't know what to think.
Even in the 80+ population most people are okay. A sample of four is not big enough to see the catastrophic effects even fairly small hospitalization numbers have when millions get infected.
This is exactly my point, and yet my comment gets downvoted.
People seem content with vaccines, meanwhile I want to understand WHY some people fair better than others. There's a far better solution than vaccines to be found, if people are willing to ask the question, and look for it.
