#41: Leave It Be
No matter how bad or scary it may look, or how painful it might feel, if you have an object stuck in your body – leave it exactly where it is and seek emergency care immediately. Never try to pull an object out of your body or adjust it in any way, no matter how painful it may be.
In many cases, the object lodged into a wound is blocking off your veins and possibly arities, keeping them from bleeding out. If you were to remove that item stopping the bleeding could be impossible before you get help. This is definitely a life-saving tip!
