It’s 2035. You have a job, a family and you’re about 40 years old. Welcome to your future life.      Getting ready for work, you pause in front of the mirror, “Turn red,” you say. Your shirt changes from sky blue to deep red. Tiny preprogrammed electronic（智能电子元件） is rearranged in your shirt to change its color. Looking into the mirror, you find it hard to believe that you are 40. You look much younger. With amazing advances in medicine, people in your generation may live to be 150 years old. You’re not even middle-aged.

   As you go into the kitchen and prepare to pour your breakfast cereal into a bowl, you hear: “To lose weight, you shouldn’t eat that,” from your shoes. They read the tiny electronic code（电 子源码）on the cereal box to find out the nutrition details. You decide to listen to your shoes. “Kitchen, what can I have for breakfast?” A list of possible food appears on the counter as kitchen checks its food supplies.

  “Ready for your trip to space?” you ask your son and daughter. In 2005 only specially trained astronauts went into space—and very few of them. Today anyone can go to space for day trip or longer vacation. Your best friend even works in space. Handing your children three strawberries each, you add, “The doctor said you need these for space travel.” Thanks to medical advice, vaccination shots（防疫针） are a thing of the past. Ordinary foods contain specific vaccines. With the berries in their mouths, the kids head for the front door.

   It’s time for you to go to work. Your car checks your fingerprints and unlocks the doors. “My office. Autopilot,” you command. Your car drives itself down the road and moves smoothly into traffic on the highway. You sit back and unroll your e-newspaper. The latest news downloads and fills the viewer. Looking through the pages, you watch the news as video films rather than read it.
