The article talks about how in our "super safe" modern society kids no longer have a chance to play with knives, saws, etc. As a consequence, they may grow up with an unwarranted fear of these tools. By comparison, cultures that are "less modern" aren't afraid to let five-year-olds try their hands at field-dressing an animal with a sharp knife. Are we doing the kids a favor by protecting them from any sort of risk?
