We have seen the Terrible might of Force Lighting, (Poor Mace Windu is not a smoking piece of Bacon.) We have seen Force Push, Force Speed, Force Rage, Force Healing, Force Vision, and very impressive Force Reflexs when it comes to Lightsaber tatics and abilites, other powers have also been hinted at inculding the abiltity to keep someone form experienceing death. Thinking about that, could it be possible that in Episode 7, Mark Hamill's Luke Skywalker figures out the trick and uses the Force to transform himself back into a young man in his early 20's........... At this point anything is possible with these new Star Wars Movies !!!!
