As I've said, it's not in the technology but in the Will. In 1969 I was living in an insulated building that was heated by a drip-type oil stove, over which we cooked. I slept, in cold weather, in a down sleeping bag under two good wool blankets. There was no airconditioning in the summer, but I did have an electric fan. Scotch whiskey -- JW Black -- was US $5.00 a liter. We ate and cooked communally.

Of course, in 1969 I was in the Army....
