You stepped something sharp, and crusty-rusty; And your feet bleeds! Danger starts, and there, tetanus comes in. It might look like a relatable "oops" moment. But it can be sneaky! Tetanus makes you arch your back uncontrollably, and even your jaw! That's why some people also call it "jawlock." Better use shoes when going outside, especially when the outside have those seemingly harm-less, crusty-rusty metal. This is what tetanus is.
