Clearly there are always generational changes and we should be sure to note that not all the aspects of iGENers are negative.In fact, today's teens are physically safer than teens have ever been. High graduation rates are also up and the teen birth rate hit an all-time low in 2016, down 67% since its modern peak in 1991. Nonetheless, psychologically speaking, today's teens are more vulnerable than Millennials were: rates of teen depression and suicide have skyrocketed since 2011. Twenge traces much of this deterioration to smartphones.But I'm hesitant to go that far.I mean what other things could be affecting today's teens besides the fact that they, and often their parents too, are addicted to their phones?
