Sandseter and Kennair analyzed the kinds of risks that children seek out when adults give them some freedom, and they found six: heights (such as climbing trees or playground structures), high speed (such as swinging, or going down fast slides), dangerous tools (such as hammers and drills), dangerous elements (such as experimenting with fire), rough-and-tumble play (such as wrestling), and disappearing (hiding, wandering away, potentially getting lost or separated). These are the major types of thrills that children need.
