[Osborn F Enready]

Mind over matters exists to a point.

Any good powerlifter will tell you that.

Some days the same body with the same diet, rest, etc can lift "x" amount of weight, but on other days can lift nowhere near "x" because they can't find their mental zone.

I don't think its anything more than tricking the mind however, not tricking the "matter".

I think the mind can be fooled to increase adrenaline, or alter body chemicals a bit, but, not in the power to levitate matter or "cure" disease like some magical mystery.
