Thank you very much, I like food for thought too.
That mortgage bit is one of our most valued trap... don't get me wrong I have one too but we have become a people who is working to live in overly expensive homes. That is why I like the idea of self building and earthships or other kinds of sustainable structure where materials cost nothing and utilities are cheap.
As far as this "Survival" charity is concerned I'd like to check it out. It does bring something I heard to mind.. a part of re-wilding is to teach ourselves, domesticated humans, how we could live in the wild. We can be looked at a bit like how zoo animals don't have the necessary skills to go into their wild habitat, neither are we.
The indigenous human is almost extinct, and I don't hear too many people talking about saving the humans...
