Hi, good day, If you just looking for some ideas for your speech, I guess you need to discuss the differences between the old people and the young in the attitude, priorities, and views among generations. i see the differences also appear in some other ways. For example, the way of entertainment, the way of thoughts, and many other issues such as music, morals, and goals in the life ... for sure our grandparents generation never understood how fast we need to think or even how fast we need to finish our life ... :)
