How to Prevent an Injury While on a Staircase

I fell down a flight of stairs when I was a kid, the only thing I remember is being at the top with my parents and grandparents below looking at me, and then waking up with them holding a knife to my head and being terrified. They did that because it was common to do, because the knife was cold and kept down swelling, but, I did not realize it at the time. But, yes, we do need to pay attention to how walk down stairs correctly, remember the whole story with Johnny and the model? I have actually had friends die from falling down stairs. But, still, this seems suspicious with Ivana for some reason.... maybe I just don't trust the media.
