But you know, it's a thing where you gradually get sensitized over time, so you can have no reaction, no reaction, no reaction and then one day: reaction.

But OTOH, I guess the fact that you don't have a reaction right now means at least you don't need to sweat it if you brush against it. But I wouldn't keep up the bare-handed weed removal.

(But in fact, what do I know? You might stay completely immune)
