Good thread, we always need a reminder of the risk in our endeavors and how we assess it. It is good you are aware of this early in your kayaking life and what I assume is your life in general. Even when, or especially when your impulse control is not fully formed. One caution I would make in your risk assessment is to not buy into the saccrine pabulum that you will die doing something you love. No, to use the skiing analogy, she died because lots avalanching snow crushed her against a tree. She died in agony and flashes of searing pain.
Or in kayaking terms, fighting to get out of your boat and get a breath totally immersed in liquid. Or in a wheelchair, older after you landed that huge falls wrong. You wont love it in your last moments, as far as we know. The heuristics of avy safety are appropriate: peer pressure, accompanying experts, familiarity with the run, etc., are cautions we need to be aware of. Make it your study. For a long time. Have fun!
