"Some recent research suggests that, by thinking about death so often, the Bhutanese may be on to something. In a 2007 study, University of Kentucky psychologists Nathan DeWall and Roy Baumesiter divided several dozen students into two groups. One group was told to think about a painful visit to the dentist while the other group was instructed to contemplate their own death. Both groups were then asked to complete stem words, such as “jo_”. The second group – the one that had been thinking about death – was far more likely to construct positive words, such as “joy”. This led the researchers to conclude that “death is a psychologically threatening fact, but when people contemplate it, apparently the automatic system begins to search for happy thoughts”."

What other word besides JOY starts with JO???
