Kelly, Before I can answer your valid questions, I have one for you. What is a "normal ability"? The whole concept behind ESP is that everyone could potentially tap into this unused resource in our brain. This is why I suggest you try it yourself.
I have briefly talked about locating people with my past mentor sometime ago now. I have some rough idea where to start but even with a natural ability, it is useless without a good technique. Everything connected to humans has evolved and improved over time, even thinking and logic for example. It would require a lot of my time to develop this independently. This is one skill out of dozens of known phenomena, and there are still limitless of unknown ones too yet to be developed. If you have looked into energy practices such as Qi-Gong you will notice that the technique has practically not evolved at all since it was established and there is only "one way of doing it", this I believe to be false not to question and improve upon something which dates back thousands of years.
I really hope you can see my view-point on this and see if it makes a little sense.
I hope that once I have established myself as genuine you will take my words more to heart. Until then, take it as you will. I force feed no one. I only ask for everyone and anyone who takes an interest in ESP to experiment for themselves before they apply straight-up knock'em down approach. Perhaps I am naive in my belief's, but regardless I see the practicalities and possible usages for the world we live in today.
I'm off to bed now. I hope that this has partly answered your questions. I will elaborate and answer any more questions you may have when I am able too
