For certain things it's out of this world (literally I guess). But then I tried for almost a decade to reverse my balding without implants and it seems to be impossible.
It shouldn't be. I've manifested "impossible" things before. It just seems for as much power as we're able to access with this, certain things are off-limits (you can't manifest eternal youth or youth until the day you die, for example, and I dare you prove that you can).
Having gone through that realization and the experiments to realize all that, I became jaded with the whole affair, and only use it to make life easy, then coast along.
