Cars, also not 100% safe. Going outside, also not 100% safe. Walking up and down stairs, also not 100% safe. Where are the Anti-Car, Anti-Nature, and Anti-Stair movements? Yes, this is a bit tongue in cheek, but you get what I mean. Absolutely nothing in life is guaranteed safe, even drinking water. You can choke on it, or drink too much, or it can have something in it that kills you (ala Flint).
