We only have one type of "poisonous" snake 🐍 in Norway, and I doubt it is able to kill anyone, and it is seldom seen.
I remember that when I was a child, we were picking wild berries together with our grandma, and suddenly one of those snakes (hoggorm) appeared, but grandma took a large stone and threw it on the snake, and it disappeared. She was a tiny little woman, but yet brave. 😊
