Back when I was growing up sailing there was one day that I will never forget. I was sailing downwind in a
dinghy when I reached over to assist my crew with the centerboard. With a slight wind shift and a small distraction I turn the rudder just enough to cause the accidental jibe. The next thing I remember was laying in the bottom of the boat with my head covered in blood. It turned out that my injury was not severe, but if my head was half an inch closer to the end of the boom I could have woke up in the ER. So ending the day with a small gash on the top of my head and one lesson to never forget. Take extra pre-caution when sailing downwind, always know the wind direction, and pay attention.
