habitus - I think what he meant is that when our car-centric world falls down on around our ears, the people that are living closer to the earth - IE without the insulation our technology provides us from nature - will survive it fine. How many people in the city don't even have a place to grow food for sustenance? We'll all be fighting over canned goods and twinkies to eat, they will live exactly as they have lived for centuries.
Those of us that survive the collapse will sit and miss what we had before. We will miss the internet. We'll miss Lasik. We will piss and moan and cry "WHY WHY WHY WHY" to the sky. They don't have anything to miss.
I don't know, I'm not carpediem, but that's how I took his post.
