In 2040, many technologies will develop more rapidly than now. For example, transportation will be better, and we will be able to go somewhere we want to go, especially foreign countries much more quickly. Moreover, most things around us will be more convenient and user-friendly, so they will help our lives more than now.
By the way, in 2040, I will be 35 years old. If I am lucky to have a wonderful husband, I may have some children and spend happy time. And I hope to have a motivative job and enjoy working. I want to live in Japan now, so probably I live here. However, I cannot deny the possible of living in an European country because many people around me says " You should live in Europe."
