With age, as time begins to be perceived as limited, priorities shift towards goals with direct emotional meaning. People become more selective in their relationships and activities, focusing on connections and experiences that provide a genuine sense of satisfaction. Research also shows the so-called "positivity effect," where older individuals tend to focus more on positive emotions and experiences compared to negative ones. Brain imaging studies have indicated greater activity in areas of the brain associated with emotional processing when dealing with positive information. Several studies concluded that older people report lower levels of anxiety, anger, and sadness compared to younger individuals, as well as better emotional self-control and greater empathy and gratitude. Researchers believe this shift reflects a reordering of priorities with age, when the focus becomes greater on what gives life meaning and psychological comfort. Studies in positive psychology have shown that many people become more satisfied and happy after reaching their sixties, despite the health and social challenges that may accompany aging. Researchers attribute this to a change in priorities and perspective on life. Numerous studies have identified a U-shaped relationship between age and happiness, where well-being levels are relatively high in youth, dip in the thirties and forties, reach their lowest point around age fifty, and then begin to rise again. Data collected in over 145 countries between 1973 and 2017 show that many in their early sixties reported life satisfaction levels that matched or even exceeded what they felt in their twenties. The American MIDUS study, which tracked adults aged 25 to 75 for a decade, found that life satisfaction remained relatively stable until the forties, after which it increased significantly until the sixties, described as the peak of psychological well-being for many. Despite this result seeming unexpected amidst declining health or stable income during this phase, researchers have dubbed this phenomenon the "paradox of aging," where the subjective experience of life improves despite the decline in some objective conditions. Psychologists explain this through the socio-emotional selectivity theory proposed by Stanford psychologist Laura Carstensen, which posits that a person's awareness of time's passage influences their priorities. In youth, when time seems vast, many focus on acquiring knowledge, embarking on new experiences, and expanding their social networks.
