In my opinion I think the life will change too much in 2100, maybe there will be cars flying or things like that, the people will be able to go to others parts of the world easier, maybe with a new kind of plane, but nor like the ones we actually now, but neither the films ones. People would have change their habits for example, they could eat extrange food  or packed food, it can be awesome. The sports will change too, it will be more secure than now. the medicine will improve so much, and I hope that there would be a treatment for sida and cancer.

Aquí la tienes, te hablo sobre bastantes temas para que sea más dinámica, pero es dificil hacerla con tan pocas palabras xD
