Susan Pinker explains why face-to-face contact matters in our digital age:

Our survival hinges on social interaction, and that is not only true of the murky evolutionary past. Over the last decade huge population studies have shown that social integration — the feeling of being part of a cohesive group — fosters immunity and resilience. How accepted and supported we feel affects the biological pathways that skew the genetic expression of a disease, while feeling isolated “leaves a loneliness imprint” on every cell, says the American social neuroscientist John Cacioppo.

And here’s the problem: being “more social” online doesn’t help:

Recent MRI studies led by neuroscientist Elizabeth Redcay tell us that personal contact elicits greater activity in brain areas linked to social problem-solving, attention and reward than a remote connection. When the identical information is transmitted via a recording, something gets lost.

I guess catching up for coffee is still better than texting.
