    And you'll find that fructose is the hardest of the simpler sugars for humans to digest. In fact endurance athletes will avoid it almost entirely since it creates havoc in the intestinal system while under stress. Even while not under stress. Many have had the experience of getting the "shits" from eating too much fruit, and you'll be hard pressed to live on it, with the possible exception of the banana, which ought to be revered.

    Starches, such as found in grains and tubers, in the presence of sufficient water, will digest nearly as fast as sugar, which we derive from. . .a grass. Which is lovely to eat raw.

    Oddly enough, we seem to be better tuned to water plants, such as rice, than land plants, where you'll also find fish. Go figure.

    No, things aren't simple, and we're essentially omnivores, but If I had to choose one thing to live on entirely it would be fresh, green rice. We seem designed for it. If I could have two things I'd add bananas, which we also seem tuned for, in moderation. Any decent survivalist can tell you you run the risk of starving to death on a diet of fish, even fairly fatty ones like trout and salmon. The Inuit also eat a lot of seal, whale, etc.

    Every try eating raw, unground grain?

    Sure. I've tried wild rice, millet, and amaranth in the raw form. Not bad really, although I do prefer it cooked. I don't like raw termites either, although they are a staple food of some. I'm told I used to have quite a taste for ants though.

    You'll find my kitchen contains a fair amount of these grains in their preserved by drying form, which necessitates my cooking them to return their natural moisture content, and yes, most the vitamin C is gone by not eating them in their raw, green form.

    I'm curious, why do you suppose early agriculturalists, around the world and independantly, would go to such great lengths to domesticate grain if they didn't already consider it a staple food? It seems a pretty daft thing to do if you're already living on bananas and papaya.

    If you wish to sell your risk to someone else you must have sufficient funds to do so, no? The risk buyer has carefully calculated his own risk to come out ahead, otherwise why would he buy risk?

    It isn't an all or nothing thing, but this "capitalist thing" is essentially about taking your own risks. Even selling your risk is a form of risk. If you don't suffer a loss, you lose.

    It's about being responsible for yourself. Not about making a lot of money. The notion that it's about making a lot of money is a fairly modern myth. You can arrange things so that you take less risk for lessor possible returns, but even if you just want to run a simple lawn mowing business to make ends meet nobody is going to buy the risk that you won't be able to find customers.

    The social structure under which risk is distributed in such a way that you are guarunteed a salary even if you can't find customers is called socialism, but socialism, while it restricts your risk, sells that risk to the general populace, who then have a right to tell you what risks it will, or will not, tolerate you takeing.

    In any case, the idea of risk is relative. If you start out with nothing you naturally have less to work with. If all you want to do is mow lawns, and all you have is $100 in your pocket, well, you're going to have to find some crappy old used mower, fix it up as best you can, eat Ramen noodles, and work your way up.

    If you've already got $100k in the bank from somewhere, well, it's damed sight easier to spend a few hundred bucks on equipment and just eke out a continuing living without having to worry about where tomorrow's meal is coming from.

We require far less protein than most other predatious creatures, like cats, dogs and . . . rats.

Our physiology is hardly unique, but it seems to have an odd sort of pliablity that gives strength. Like the reed bending in the wind.

    Note that I did not say "without oil." I know perfectly well where my bicycle tires, and the plastic shell of my bicycle saddle, come from, as well as the energy burned to create the high quality steel tubing from which it is made, and to deliver that tubing from Italy or England to my home in America.

    However, the amount of oil used to lubricate your sewing machine for hundreds of years is expended in a single automobile oil change, and easily derived from locally produced vegetable sources. One ear of corn a year ought to do it.

    My bicycle saddle is a nonconsubable. I will be able to hand it down to my kids in 30 years, and I've already used it for 30. The amount of rubber in my bicycle tires is about that in a couple of tread blocks of an automobile tire, much of the rubber, and its entire carcass, are from natural sources (latex and silk/cotton). I use about 3 oz. of grease in my bicycle every 10 years or so, and I'm the sort that completely strips it down and rebuilds it four or five times a year, seeing as how I travel about 10k mile/yr in all weather. Nevermind what I save in oil compared to casting and machining a single automobile's engine block.

    About 20 gallons worth of gasoline covers my bicycle oil usage for life.

    My treadle sewing machine is over 100 years old. thus its manufacture does not go against my personal consumption of oil. It works as well today as it did 99 years ago. Again, I'll hand it down to my kids. The only thing I've ever had to replace is the leather belt. If I were to design a new one I'd probably use a toothed rubber belt though, that requires oil to manufacture. It's a better sewing machine for patchwork and fine tailoring than any electric machine I've ever used, and I've used just about all of them ( I was a sewing machine salesman for a few years).

    Again, I didn't say anything about not using oil. I said foreign oil. Nor does much of that oil need to come from petroleum stocks, so little of it is used directly, and much of that is in the form of nonconsumables.

    Oil was used to make them. Oil is needed to use them. But no. not much oil. As much oil as is needed to make 22 pounds of machine, in the case of my bicycle, as oppossed to 22 hundred pounds of (oil consuming) machine in the case of a crackerbox Hyundai. As much oil was consumed in shipping its bits to me as is consumed in shipping 30 pounds, not 30 hundreds of pounds.

    And my bicycle even provides some of my electric power. When I'm riding a stationary trainer, why use a wasteful source of resistence when I can use a generator just as easily?

    Not to mention the fact that what I save in liablilty costs alone in a few years pays for all of my human powered devices for the rest of my life. Which means I don't have to work at all to make that money if I don't choose, which means I don't have to do the oil burning commuting to do the work either.

    Tell ya what. I propose a race. From LA to NYC. We each start with 500 gallons of refined oil. You use yours to make a car and drive it to NYC. I'll use mine to make a bicycle and ride it to NYC.

    I figure I'll be sipping a latte in Tavern on the Green while you're pushing your, whatever it is you manage to whip up vaguely resembling a car, through Pasadena.

    Good luck with the Rockies.

    Yes, I'll use oil. But not much. I'll have some left over on account.

    Since we live in an oil economy we could even translate this into purely monatary terms, since each dollar represents a certain amount of energy. Thousand bucks apeice (roughly analogous to 500 gallons of refined oil). Ah, seems like you're stuck in LA. You're a little short on your oil budget. And there I am, in Tavern on the Green, sipping my latte, although I did have to subsist on rice and lentils to fit the entire trip into budget. That's ok. I like rice and lentils.
