Why do people need to change their magnetic field? For example, if a person gets sick, a doctor diagnoses, prescribes medicine, and treats the illness. Similarly, if our destiny is sick, we also need to diagnose and prescribe medicine to treat it. We can't change what's innate, so we can compensate and adjust it later in life! Whether it's seeing a doctor when you're sick or trying to change your destiny, it's best to be guided by professionals, not by "desperate measures"! Specialization is key! Don't easily use yourself as a guinea pig.
