Discovery Channel Program: Scientific Look at Tracking Souls to the Afterlife

The Discovery Channel program called "Through the Wormhole," hosted by Morgan Freeman has a very interesting episode called "Tracking Souls to the Afterlife." Looks like a very interesting program.
 - As a scientist myself, I believe that the energy within us has to go somewhere when we die. For energy cannot be destroyed, only transformed. That's when we choose to remain earth-bound as a ghost (which we will later regret and try to move into the light), or just move into the light and become a spirit.
  I'm always looking for more scientific evidence. This is worth watching.
