Say you were choking on some food and you couldn't breathe at all. Some stranger next to you, who is not certified to perform the heimlich maneuver, does exactly that to dislodge the blockage in your trachea. In the process of performing the heimlich maneuver, he breaks a few of your ribs and bruises your intestines. You require medical service from the hospital and your insurance will only pay for 15%. Would you sue him for the remain hospital charges?
