Your Brain on Social Isolation

Social isolation is human despair. We evolved down from primates who were all blessed and sometimes cursed with group membership. Simply put: no (hu)man is an island.The strangest, and some ways most disturbing, example of social isolation I ever experienced was as a senior officer on a Coast Guard ship were I was sent for a very brief tour. It was during the Vietnam war and I was serving in the Public Health Service. A requirement of that service was to do a 3-week junket providing medical coverage for a small sector, in the North Atlantic —the Sea of Labrador—as part of America's commitment to NATO.
