I live alone in the woods, and have no social contact with anybody. Basically, I withdrew from society about six years ago. Although I am fairly deep in the woods, I am close enough to civilization to shop for food once a week, and to have internet, TV and telephone. I talk to my kids, who live elsewhere, over the internet once every couple of weeks.
It is fun to collect mushrooms and pick berries, but I wouldn't want to rely on hunting/gathering for my sustenance. By the way, I once had a very successful career and have saved enough money to meet my basic needs for the rest of my days.
The silence/sound of the woods is, to me, sublime, and I find nature very beautiful. However, I now think that withdrawing is not such a good idea. I had no history of depression, but over the winter was somewhat depressed. Now that I have abandoned all my friends and business connections, re-entering society will be difficult. I am thinking of doing just that though, albeit in a very limited way.
