Kryptonite is Always Superman's Weakness

You do still know that "rock"is dangerous to humans too, right. It might take much longer, but it still kills them if they get exposed to it too long. Superman's just more susceptible to it's radioactive properties because it's native to his species. It's literally their natural bane. I know you feel it's overrated and all, and i still understand why. But i still feel the need to remind that Kryptonite isn't just a "rock".
