    Things like BPA or certain types of food are really only going to be corner cases.

    That seems very unlikely. It was suspected for a long time that BPA signaling your system to keep creating fat was causing some real problems.

    Your body cannot store fat from nowhere.

    That's technically true... It will always be possible to diet and lose weight. But if BPA is acting as described, then you will have to carefully watch your diet, forever, because your body will ALWAYS continue to signal hunger, and always try to store fat. And it's a tricky balance. It's easy to diet too much, and end up getting dizzy and even fainting from too few calories.

    So, if BPA has made an epidemic of anything, I'd say it was more like an epidemic of being "slightly chubby", but not one of obesity.

    Maybe you don't know what "obese" means... If you really mean MORBIDLY obese, then I'll agree with you. When weight becomes crippling, a little self-control is necessary, and it's easy to judge by eye when you're gaining hundreds of pounds, versus losing it (too quickly, perhaps).

    But obesity is really just a few pounds of extra weight. Someone doesn't even have to appear out of shape (when clothed) to be obese. A few pounds of belly fat, and you might be obese, and at high risk of a number of health problems.

    People cook these foods precisely because uncooked food is hard to digest. And it's not likely people are going to be ignorant of this fact... eating raw vegetables is tantamount to drinking a mega-dose of Metamucil. It'll be PAINFULLY obvious if you're not digesting your food.

    While there are exceptions, like foods very, very high in fiber... I don't know of any all-bean diets, so for the average person, all calories are pretty damn close to being the same, for all practical purposes.

    First off, it's been solidly proven that BPA will shrink your genitals, just as if you've been taking estrogen pills. That's something which might be a reasonable trade-off in powerful medications, but that should never be something that comes into contact with our FOOD, which by definition, should not have such medical side-effects.

    And back to your claim, exercise has very little effect on obesity. You have to run a marathon to burn off a pizza. It's massively impractical to lose weight with exercise.

    So we're back to over-eating. But is this generation really forcing themselves to over-eat? It's really not like every family out there drinks nothing but sodas, and eats nothing but junk food. The fact that obesity has become an epidemic, and this generation is estimated to have a shorter life-span than the previous, indicates that something has change for the worse.

Set it to "offline mode" and when you hit a key, it'll appear on the screen, so it can be checked. They require power, but with no smarts, and a pretty tiny CRT, it's a tiny fraction of a computer. And if you get a multiport serial card, serial mux, a bunch of USB-RS232 adapters, or a terminal server, you could hook them all up to a computer, running whatever text-only typing tutor program you've got. If there's any long-standing call / order processing centers in your vicinity, you might find that they've stockpiled their old terminals as they switched over to computers.

    A second option would be pretty much any old PDA with a keyboard... All the better if you go with a B&W screen without backlight. Something like a Psion 3/5 or Osaris will run for 40+ hours on a pair of AAs. String some wires from the battery compartments and supply them with 3V (should be simple enough if you've got a car battery handy) instead of going through batteries, and you should be fine. The WinCE devices out there are almost all high power, due to color screens and faster CPUs, but could still work for you, if you can secure a good number of them.

    It wouldn't be hard to build a simple circuit that takes PS2 input, and outputs the letters to a small LCD, but since there's no such mass-market product, I think it'll end up costing more to get someone to assemble it, than it would cost to buy used junk.

But observing a fact doesn't require science, so this really isn't as all relevant to the scientific method.

We went from bleeding sick patients, to treating them with cure-alls like cocaine, laxatives, and snake-oil. It absolutely isn't true that one theory was more correct than the one before it, and that the next one would be even better.
