Im kinda in two minds with this, i don't believe they can predict the future cos as thief said the future is big, and we make are own future through are own actions. You do get some people pretending to be physic, which is unfair to those who do believe in it, cos they are being takin advantage of.

But i do believe in mediums and the afterlife i just cant except that you live life and then die and that's its.
