A couple of posts just trounced on a seemingly good discussion to be.

As for "We can practically live a day (or many) being ?socially? active without seeing a human?s face."

I couldn't. Unless I am playing 'get away' in the mountains, then I've gone more than a month without seeing people, OH THE TRANQUILITY of not seeing or talking to people for a while!!! No phones, no TV, just a few flats of beer and some tree roots to trip over at night.
