You are right, I am only 99.99% certain. It’s the only time I’ve been sick in the past 30 years.
The idea that dose matters a lot goes back to Paracelsus, the father of toxicology, in the 16th century. It is similar with infectious agents.
By all means, you go without a mask and get sick, and I will wear my mask in public and stay well. It’s fine with me. That’s freedom in action.
The person who sneezed near you could’ve had allergies, and there could’ve been a different person (who didn’t have obvious symptoms) sitting near you that got you sick instead. The best you can really say is that you got sick from *someone* in your vicinity that day. You may be right, but your 99.99% certainty is hogwash.
I do wish you stay well, and enjoy wearing your mask. I think it’s awful that you want people who choose not to wear one to get sick. That’s pretty weird, and a great example of what CoVid-only obsessiveness has done to our society. It’s the first time in history that when people got sick (from CoVid), they were met with anger or glee instead of concern and compassion.
