The stereotype of grumpy old people apparently doesn't hold up under closer inspection as a new study from Duke and Vanderbilt University psychologists has revealed that older people are generally more emotionally stable and better able to resist temptations in their daily lives. The study was published in the journal Emotion. The researchers pinged 123 study participants aged 20 to 80 on their cell phones three times a day for ten days. Participants were asked to indicate how they felt on a five-point scale for each of eight emotional states, including contentment, enthusiasm, relaxation and sluggishness. Then they were asked whether they were desiring anything right then, including food or alcohol, cigarettes, social media, shopping, talking to someone, sex, sleep or work. They could report up to three temptations at once. Each participant had also been assessed on a standard measure of 'global life satisfaction,' which determined their general well-being, regardless of the moment-to-moment moods.
