SAN LUIS OBISPO, CA—The inconsiderate residents of the apartment above Jim Bracker, 23, woke him from a sound slumber several minutes before 3 p.m. Monday. "Christ, quit with the aerobics already," a groggy Bracker shouted toward the ceiling. "You've been jumping up and down for half an hour!" Unable to return to sleep, Bracker resigned himself to channel-surfing until he was forced to drag himself into the shower and ready himself to meet a friend for a 5:15 p.m. movie.
