friends doctor basically told her to microdose viruses

a friend of mine is also very covid serious and consistently wears a high quality mask outside home. at a doctor appt she asked the doctor if her immune system would be hurt by wearing a mask all the time for years. Doctor said yes and encouraged her to stop masking in her building outside of her apt so she could get exposed to germs and viruses. This is NYC, where most of our buildings are old stone/concrete with no airflow (no ventilation, no filtration, rarely even a window that opens) and in common areas (hallways, lobby etc) youre sharing air with 100s of other people. just big boxes of CO2.

does anybody have studies that show that its basic nonsense to expose yourselves as a way to make yourself healthier? especially since we know the damage that COVID, RSV, and these new variants of the flu are doing to people.
