“That’s not really how it works, mom.”
“That’s not what my doctor says.”
Love visiting with the Parents!
“Wearing a mask” and “living your entire life in a clean room” are hardly equivalent risks.
You don’t need to be exposed to large viral loads to build immunity, you can actually build immunity with very limited exposure as long as the immune system is activated to some extent. Exposure level determines the severity of the illness, masks allow people to limit their exposure without hermetically sealing them off from all exposure entirely. Less sick, same immune response.
I mean, that is how it works, your immune system needs to be regularly exposed to things to stay active and function properly.
That’s the immune system as a muscle myth, comrade. That’s really not how it works. Most immunity you gain from one pathogen does not carry over to unrelated pathogens. And much like Covid demonstrates, there are a number of pathogens that do damage to your immune system.
What you need to understand is that millions of doctors out there are like this
being a “professional” in anything is utterly unrelated to reality. Think about how much of a failure Boeing’s planes are, and now think about how much stupid shit doctors can get away with because there’s no threshold for hard failure
