If you could go decades ahead in time and ask your 40-year-old self some questions, what would you ask?

Why? Be as specific as you can. What questions would you have about how your life turned out? About the lives of loved ones? About local, national and world events? Inventions? Arts and culture? How would you answer the question? These teenagers had time for only a sentence each, but you have more room. What are all the things you’d want to know? Why?
What do you hope your life will be like at 40? Why? Are there questions about the future you would not want answered? What and why?
