Honetly I agree that anything is possible, and so if anything is possible that means something could be impossible... See where I am going with this. I learned this paradox today or at least how he described it and it makes perfect sense.
You guys are making up excuses, to validate claims or abiliies that are extraordinarily rare, if they do indeed exist. If you want to keep trying at it... be my guest but I can only warn you out of friendly advice you will drive yourself insane, being that insanity is trying the same action over and over as many times, and expecting a different result or outcome everytime, that result being that you would like to succeed.
If these abilities or powers were real, at least real enough they considered to be signifigant you wouldn't be sitting here asking these kinds of questions, in which I might add have already been answered many many times on this website. And yet undoubdtedly the same questions are still being asked, as if you are hoping that one of these times the answer will change from no... to yes you can absoluetly change your hair color, eye color, teleport from here to hogwarts, change from a human being to a manfish with a tail, or become a blood sucking vampire and so forth. Magic doesn't exist so kids can amuse themselves or to make yourself seem cool to your friends. Magic like most of everything has it boundaries, it is a sacred power that shouldn't be so toyed with. Learn the basics, study and practice as often as you can, and maybe... Just maybe then you will be able to accomplish something that might actually amount for something and be worthwhile.
And yes I am saying "Seriously" seriously get with the program or find a fantasy website to read and post on...
