Many of the clients in my general psychology practice may loosely be included under the description of "the worried well." They often respond to Multiversal voyages with dramatic results which are similar to the personality changes which are observed in people who have undergone a Fundamentalist experience of "salvation" (Gibbons & de Jarnette, 1972), but without the inclusion of specific religious indoctrination.
