Ever since the movie The Surrogate, I've always thought that the movie will become real life. Basically in the movie, everyone has a robot. Everyone in the world controls their own avatar/robot through a pod, very very similar to the movie Avatar. You have total control over how you look. You can look like Brad Pitt in the morning and become Angelina Jolie by night. They can feel, smell, see, touch, and taste everything the robot does. You're basically living your life through a robot. Living your life this way, you will not face the physical harm of everyday life. For example if you get hit by a car, only your robot is damaged. The actual person is safe and sound in their pods. Although this might sound scary, I can see this being a realistic feature of everyday life in the future.
