The number one group was instructed to pray seven times in a row and given a prayer to recite and the group that had the numer two was instructed to do seven situps without stopping. Spiriually both groups was happier but the group that did the situps had more energy. He switched them and repeated the experiment and afterwards they were back on even core but now all of them needed a shower and a nap so the doctors gave them the rest of the day off just to relax. Dr. Flagyl rated that experiment an A.
