Answer to Question 1
Subjective well-being is an evaluation of one's life that is associated with positive feelings. Older adults have improved subjective well-being compared with middle-aged adults. Emotion-focused research in neuroscience is providing answers to the question of why subjective well-being tends to increase with age. Age-related changes in how the amygdala functions lower emotional arousal in older adults. It may be one reason that older adults experience less negative emotion, lower rates of depression, and better well-being. Brain activity in the prefrontal cortex also changes with age and is responsible for older adults remembering more positive emotional content.
