Ok, maybe she really was a nut job.

Drown also claimed that jazz music caused cancer and could be combatted by playing soothing tunes. In one of her books Drown Atlas of Radio Therapy she claimed that patients should not stand over a drain when taking a shower because the patient's magnetism would be washed by the water into the drain and leave the patient "depleted". When taking a bath, someone else should drain the tub water, or the patient should put on a robe and drain the water outside the tub to keep from washing the patients magnetism out with the water.
