Getting hurt a little bit is very useful.

I've forgotten about plenty of situations where things could've gone wrong but didn't but I can still vividly remember accidentally hitting myself in the dick with my bike handle.

(Since I know someone will want to know: I misjudged my speed and the impact a wet wheel had on my braking power. When I noticed I was going too fast to take a corner I braked and the front brake locked the wheel immediately. Inertia did the rest.)

That and a (thankfully merely scary) run-in with aquaplaning a few years later taught me to be wary of wet driving conditions, especially of braking in them.

Adults who can recall experiences of ultimate freedom to play in their own childhoods find it difficult to give their own children the same room for exploration [10]. In this context, research shows that if children are free to select the level of risk in their play activities, they will frequently choose a higher level than the guiding adult would predict and consider acceptable [11]. A lack of opportunities for risky and challenging play has negative consequences for becoming a healthy adult, such as learning to trust oneself, recognizing one’s limits, and knowing when it is better to ask for support [12].
