^here's a change: instead of virtual reality, try Reality
  Reality. Got video games where you move your body to fight
  virtual people? How about getting a couple of broomsticks and
  pick a friend and go outside and fight a REAL person. Virtual
  walking? Treadmill? How about a REAL walk - outside. Take a
  Claritin if you have allergies. Shut down the computer, turn off
  the adventure movie, and go out on a Real adventure up a
  mountain or through the woods. Reality is dirty, painful and
  smells funny, but it's so well worth it.^
