Adolescence interview response

During interviewing my father, he explained about his generation with lots of details, such as what has changed nowadays. I noticed that nowadays, the technologies and medical science have changed and flourished a lot compare to my father's generation. Also, according my father explained about the adolescents in his generation, the adolescents in my father's generation and my generations have similarities and difference. The similarities were most adolescents like hanging around with friends, care about their grades and like to play sports(for boys). The differences was the knowledge because the adolescents in my father's generation had only books to study or improve their knowledge.(Nowadays, because the technologies have developed a lot, we know more knowledge than the adolescents in my father's generation). In short, I think the adolescent today is harder than my father's time because we have to study harder due to the educations became more knowledgeably and much harder than my father's time.
