As has been written about in this forum many times, quite a few of us, myself included, like to sit around and tell each other ghost stories. It can be entertaining when you are supposed to be doing other things and right there is the problem; instead of doing things we tap away on the keyboard spinning stories about how bad things will become or read the latest story that reinforces our conviction that everything is about to go to Hell in a hand basket. No wonder feelings of doubt creep in.
From Pop-Psy Platitudes 101:
What you think about you become.
Instead of fretting about all the things that could go wrong and how vulnerable I am; I try to consider specific problems and think about solutions – even if I don’t implement them immediately. Sounds pompous I know, but it's kind of change the things you can, accept the things you can’t bit (also from PPP-101)
We’re remolding the kitchen with a bunch of fancy and expensive appliances and fixtures we bought when living high on the hog out in CA – little I can do about those expenditures now so why not? But what I am also doing is really beefing up the framing (Tornado Alley here) and insulation, as well as plumbing for a hand-pump even though I don’t have a cistern and solar hot water even though I don’t have any, wiring for minimal emergency/alt power even though I don’t have any, making provision for a wood cook stove though I don’t have one – well, you get the picture. The cost of doing those things is minimal but the effect on my outlook by thinking through the various problems is great.
As Four of Swords said, I may never live to see the necessity for, or implementation of, any of these plans but in the back of my mind I imagine my children or grandchildren may and that reason alone is enough.
As far as this goes:
<<I don't see how doing all that work, sacrificing the joy of the last days of the easy oil party, is worth it if one gunshot will take it all away from us.>>
I apologies for being harsh, but that is simply a cop-out – you're listening to too many ghost stories.
<<But in the end, who the hell knows>
Now, that I can agree with.

The legitimate object of government, is to do for a community of people, whatever they need to have done, but can not do, at all, or can not, so well do, for themselves -- in their separate, and individual capacities.
