As a kid, I was allergic to everything. And lactose intolerant. Grass, trees, pollen, cats, some dogs, my allergy test had me wanting to scratch my back on the stucco walls.
I hit maybe 20 and all of it went away. I can roll in grass and dandelions and leaves, I can rub cats on my face (thank gawd), I eat tons of cheese. Itβs amazing.
