>>3296004you get vaccines and diseases for the flu and for colds, you don't fucking just tough out every time you catch a disease, or you'd legit just die
you'll never develop a defense against diseases like that, 90% of people aren't able to do that, if we were left with no medicine most of our population would die to "mundane" diseases
so no you'll not develop immunity, you'll just end up giving more money to medicine companies and if you're shilling for medicine makers then good job but other than that your logic is just wrong on every level of biology and medicine
>>3296005what causes allergy is the fact that the pollen of anemophilous plants (not only trees, same reason ragweed is causing allergy) is very small, very smooth and there's a lot of them, because the purpose is for them to be caught by the wind and get carried far away, and those cause allergic reactions in the mucous membrane of the nose, while entomophilous plants, including every rosaceae plant, including cherries, have big pollens with lots of hooks on them so they get stuck on the hair of bees, and they'd get stuck in the hair of the nose before ever reaching the mucous membrane, because they don't make a lot of pollen but they want the bees to carry them
so no, cherry pollen aren't health hazards in the slightest
