Older people are happier

The epiphany that elderly people are time-constrained. They want to spend time on things that matter because they're very aware that time is limited. 

This podcast explores the idea that happiness increases in old age. Not because of attrition or forgetting the reasons to be sad, but because an older person is more present in the now and thinking less about their future, they are more likely to recall good memories than bad ones, and they spend time with more "emotionally dense" long-standing friendships than making new friends.
