As people grow and age, it is customary for them to learn from their experiences. It is typical for their insight, judgement, and problem-solving to improve over the years. Hence, at age 12, one might think they are invincible and can leap a small creek or shimmy across it on the trunk of a fallen tree without difficulty. By your age, however, most people realize that there are certain risks involved with such an activity, and as such would opt for a different plan. You, apparently, are a slow learner. They should put a warning lable on you!
