My mom never practiced TK, yet she can generate the emotion/concentration necessary to shake computer monitors and slide laptops slightly. She only does it when she\'s being sarcastic when I\'m trying.
It may be why I can do a significant amount more than most people starting out. I\'d say it\'s not genetic, but I DO say that it\'s possible that, when training, you strengthen a part of your brain that handles it. When you have a kid, their part of the brain that handles it has the same strength as the other generation. Obviously, training 5 generations could result in an amazingly talented Telekinetic, or Psionic person.
But, that\'s just me thinking out loud again. I need to get my mom on tape moving a laptop, it\'s pretty amazing, seeing how the screen blinks when it slides.
