[Philip Kubik]

I would be careful to distinguish between challenge and risk of injury or death. Although I agree that challenge is important for growth, I don’t agree that risk of injury or death is necessary for growth, at least not for me. Personally, I am convinced that I would enjoy kayaking even more than I do if it were completely free of that type of risk. On the other hand, there are those who say that they enjoy the adrenaline rush of a risky experience.
