Hamburg (dpa) - The smartphone is becoming more and more the dominant leisure activity. This is at least apparent from the representative study "Freizeit-Monitor 2019" published by the Stiftung für Zukunftsfragen. In addition, the analysis of responses from more than 2,200 people in Germany shows that many of them have forgotten how to enjoy their free time. The intensive use of smartphones and increasing leisure time activities would also have an impact on sex life. According to the "leisure monitor", only about every second German citizen has sex at least once a month.
