Women with a male twin do worse in school and make less money than those with a female twin, a large study has found. The study, which included all births in Norway for 11 years, suggests that, on average, there are consequences when females are exposed to their brothers' testosterone in the womb. Women with a male twin were 15 percent less likely to graduate from high school than women with a female twin; 4 percent less likely to finish college; had a 12 percent lower probability of being married, and had a 6 percent lower probability of having children. It did not find men had long-term effects from having a female twin.
Mental health issues rise in Generation Z
A new study finds that Generation Z teens and young adults in 2017 were more distressed, more likely to suffer from major depression, and more prone to suicide than their counterparts in the millennial generation were at the same age. By 2017, more than 13 percent of Americans ages 12 to 25 had symptoms consistent with an episode of major depression in the previous year — a 62 percent increase in eight years. San Diego State University psychology professor Jean Twenge noted that it comes amid the meteoric rise of smartphone ownership and of social media use.
