One of the most widely noted traits of Gen Z is that they are not doing as much of the bad stuff that teenagers used to do. They drink less alcohol, have fewer car accidents, and get fewer speeding tickets. They have far fewer physical fights or unplanned pregnancies.24 These are, of course, wonderful trends—nobody wants more car accidents. But because the rate of change for so many risky behaviors has been so rapid, I also look at these trends with concern.
