Oxytocin.

This is coolbert:

As is germane to a previous blog entry"

That question asked:

"Why do the guys defending a fort in Afghanistan find living in a tiny bunker to be a blast, while coming home to America is so discombobulating for them?"

Thanks to the tip from Jungle Trader and the review as seen at the Amazon Internet web site:

"Tribe: On Homecoming and Belonging" by Sebastian Junger

"We have a strong instinct to belong to small groups defined by clear purpose and understanding--'tribes.' This tribal connection has been largely lost in modern society, but regaining it may be the key to our psychological survival."

THINK NOT MERELY PSYCHOLOGICAL SURVIVAL BUT PHYSICAL SURVIVAL EVEN MORE SO!!

"Decades before the American Revolution, Benjamin Franklin lamented that English settlers were constantly fleeing over to the Indians-but Indians almost never did the same. Tribal society has been exerting an almost gravitational pull on Westerners for hundreds of years, and the reason lies deep in our evolutionary past as a communal species."

DEVOTED READERS TO THE BLOG KNOW THE ANSWER TO THE QUESTION ALREADY! THAT INVOLUNTARY FLOW OF OXYTOCIN IN THE BODY THAT OCCURS DURING A TIME OF GREAT STRESS AND DANGER MARKEDLY INCREASING THE BONDING AND COMRADESHIP AS CONDUCIVE TO GROUP SOLIDARITY. AS WITH TROOPS ON THE BATTLEFIELD.

And you the devoted reader to the blog already know the answer to the question "why" and are so much the better for it too!!
