Broken my sternum in two places when I was 12, rib cage was completely floating in my chest. Three days in the hospital and all they did to fix me up was put a rolled sock under a piece of elastic with some Velcro to help hold things in place. When it was time to go home they told me to get dressed. I bent over to put my pants on, thought I was going to die from the pain, and passed out in the bathroom. No one said don't bend over or your sternum will poke into your lungs, guess I should have known that
