Two years ago, Yale University psychologist Laurie Santos began to wonder why students seemed so detached from their classmates. Like a good academic, she connected her observations to data — and found it troubling.

A range of other surveys and indicators have suggested that older people are also having difficulty finding happiness and connection in our 24/7, hyperconnected world.
