Jamie Miller is incredibly troubled. He may be the 13-year-old character in a fictional television show called “puberty,” but his story has prompted a broad surprise about the light-form of a disgruntled man who feels dangerously isolated. Even if you’ve never seen the four-part British drama series that has rapidly become the top streaming Netflix show in 75 countries, you’ll know that his character was drawn into a world of misogyny and super masculinity, radicalised online, and arrested for killing a female school buddy. Don Riddell of CNN speaks with psychologist John Amateur, who explains how sports can help, rather than hurting Jamie Miller.
