    I was about to point out that produce would not be useable by the poor. By the time you got it to them it would probably be rotted.

    But then I realized what should actually be happening is that the government open up a giant cannery, and just throw the surplus into there. Don't worry about flavoring or anything, just throw green beans into a giant bucket-sized tin, seal it up, and slap the label 'green beans' on them.

    We build up a giant buffer against famine in a few big warehouses somewhere that we can sell at slightly above cost in years of shortage. (Probably to food companies, who can figure out how to get it to market and how to repackage it for individual use, or perhaps a few families will show up to buy a tin to split...and if we're at that point we're in rather a lot of trouble, so people will be damn grateful for it no matter how they get it.)

    Or, in a natural disaster, we hand the giant tins over to the natural guard and let them cook for everyone.

    And then, when the warehouses are full, we throw out the oldest stuff by letting charities take it for free to give to the needy.

    We can do the same with meat, by making jerky.

    Oh, wait. This would be 'socialism' or something. Despite only interfering with the market in the sense that we think perhaps that food should not be priced like a luxury in times of scarcity.

    The males are not unfit, the females they produce are unfit. The males they produce are fit.

    Basically, females would be defective in proportion to the modified males. No males would be defective, so the modified percentage would hold.

    E.g., if we assume the generations stay the same size, and there are 100 males, and 100 females, and you introduce 10 modified males, 'evolution' doesn't effect the modified males, because they're fine and can reproduce fine...so they're constantly at 9% of the population.

    However, each generation has 9% less functional females, the female children of those males. This will slowly but surely reduce the population.

    The only problem would arise if only a small percentage of females were supposed to mate anyway, and thus removing a portion of them would had no effect on population for the next generation. But I do not think that is true, or someone would have noticed this plan wouldn't work. Usually, in nature, it's the other way around...all females reproduce, but sometimes not all males do. (Which would be fine under this plan.)

    I've found that having massively complicated rewrites is just an exercise in annoyance. Especially when you have rules working at both server and directory level.

    About the only rewrite rules that makes sense in 99% of the circumstances are things like 'Alias an entire directory into the site so there's a webmail dir or whatever' and 'Send all not-found requests to this specific script'. (And strictly speaking, you can do the first with a symlink, although sometimes that's not workable.)

    Yes, I'm sure there are circumstances where more rules are needed. Sometimes there's really weird stuff, and if you're doing a reverse proxy, you quite possibly are faced with such a situation.

    And, of course, if you're running a server and letting end users set up such a system, they might insist on the ability to add rules, which requires apache, as nginx doesn't screw around with .htaccess files. (OTOH, you can just ask them what they are running, and if it's any sort of dynamic site, just send all 404s to index.php, and, tada, magically it all works.)

    So I suspect, statistically, that something like nine out of ten rewrite rules really aren't needed. In fact, joomla comes with like 12 lines of apache rewrite rules (The actual rules, not the comments, and not counting other stuff in the file)...and really only needs three.

    Yes, it is probably worthwhile for people to drink more water than they do. (Not only because of dehydration, but frankly because it also stops them from eating and drink more unhealthy stuff.) Although not eight glasses of water a day, which is a misunderstanding of the total amount of water needed, most of which we get from food. Just drink a single big glass with each meal and that's probably enough.

    However, if people actually notice dehydration, they've either done some moderate sweating and probably should have something more than water, either Gatorade or actual food plus water...or they've got an actual medical problem that caused dehydration, like hypotension or diabetes insipidus, and while fixing the dehydration is a good idea in the short term, they do need to see a doctor. (Unless they're the elderly, who often have a 'dehydration signaling' problem, and just need to learn to drink even when not thirsty. Although doctors obviously know this and will tell them that.)

    I'm entirely comfortable with the EU's decision, because in my head, because if people are drinking water because they're constantly moderately dehydrated, that's really wallpapering over their problem.

    Meanwhile, while water does help mild dehydration, the most common kind...I suspect no one is running around trying to figure out a trivial medical problem they don't even notice, even if it is incredibly common. And I think if they are trying to figure it out, they already know the solution. ;)

    This is sorta like a candle snuffer being marketed as 'Can help put out household fires'. Strictly speaking, those will put out the most common types of household fires...but people who are actually purchasing it to solve the problem of household fires are going to be very upset when they try to use it.

    I'd be okay if the wording was something like 'It is estimated that mild dehydration is suffered by X% of the population, and drinking more water will prevent that.' or something like that. Just asserting it prevents dehydration in general is wrong.

    Especially as, strictly speaking, it cannot prevent some forms. Not just blood loss...it is entirely possible to sweat faster than your body can intake liquids via the stomach. (In such circumstances you really really really should be drinking something with electrolytes instead of pure water, but even that will not help in the long run.)

    'hyponatremia' is indeed 'not enough sodium in the blood', but it's a condition brought on medical problems. It's not the end result of 'not enough sodium', and can't be cured with sodium. Or water. Or anything except treating the actual disease causing it.

    Not enough sodium means you as a person are technically hyponatremic, in that you lack sodium, but that, strangely, does not lead to hyponatremia. From what I understand, if you do not have enough sodium in your body, your body stops putting fluids where they need to be and you get hypovolemia. Which has basically the same symptoms as hypovolemia caused by lack of water. (Although you're right in that I was a little confused in my other posts, as I wasn't thinking that isotonic dehydration also leads to hypovolemia, so me talking about hypovolemia was very confusing.)

    And 'dehydration' means 'deficiency of fluid' in medical terms, so, hypovolemia does count.

    As for the rest of it: Subclinical dehydration may indeed be extraordinarily common, and it's for exactly that reason that I somewhat doubt it's what people think of when they mean 'dehydration'...the reason it is so common is that people don't realize it happens. (And, in fact, I skipped right over it when talking about the 'most common' dehydration, despite the fact I already knew about it.)

    If we assume dehydration is not use medically, but colloquially, water can indeed prevent thirst, but it's rather odd that anyone would need this information at all, so I see the logic in banning it so as not to cause confusion with the medical term. If we assume it's meant medically, yes, it does stop mild dehydration, the most common form of actual dehydration...but that isn't what people think of when they think of 'medical dehydration', which is near 'moderate dehydration', so that's confusing there also. (And it's not the right solution for moderate dehydration.)

    However, reading the article about this, instead of what I had assumed their objection was, it appears the EU had an objection because of the fact that many forms of dehydration are simply symptoms of an underlying disease that cannot be cured or helped by pure water at all. (And some that can't even be helped by water and electrolytes.)

    And thus if you are actually 'suffering' from dehydration to the extent that you wish to purchase something to control it, you need to fricking consult a doctor instead.

    But that doesn't really change what I said. Although it is a good point that 'something' can be alcohol instead of salt. (And as alcohol removes water instead of adding salt, it works slower, hence the whole 'overnight' thing.)

    My point was that no one ever reaches 'Too much salt, not enough water' naturally. They have to either have a medical condition or ingest something that does that.

    Although, technically speaking, no one reaches the opposite position of 'Too much water, not enough salt' without ingesting things or being sick also. Unless you are ill, your body is smart enough to keep your body in balance, and make liquids leave the body in correct proportion to keep that balance.

    However, people very often end up imbalanced by 'My body is indicating I am thirsty due to sweating, thus I must drink some water'. Without the person realizing their body is actually low on salty water, and drinking pure water is just going to make things weirder.

    Or, as the most common real world situation it comes up in, inadvertently drinking salt water because you've been swimming in it.

    If you do that and become dehydrated, you should drink straight water.

    Otherwise, you're either missing just salt, or salt and water, and you should drink 'salty water', aka, water with some electrolytes, aka, Gatorade or other such drinks, which gives you both water and salt in the correct ratio, and your body can fix your salt vs. water balance using that.

    You do know that there are three types of dehydration and water alone will not help two of them, right? Dehydration, despite the name, does not mean 'lack of water'. Dehydration is the word for homeostasis imbalance, which is when your body does not have enough salt water.

    The most common type of dehydration is actually hypovolemia, which is not having enough sodium. So when people are dehydrated, they almost always need electrolytes (It's what plants crave!) and water, not just water alone. Drinking water alone can, in fact, make such problems worse.

    The type of dehydration where people are just 'out of water', and thus can be solved by just adding water, is actually pretty rare for people to have. And it's usually a sign of an actual medical condition (As opposed to sweating out salt that needs replacing, which is perfectly normal.), so just drinking water is hardly a 'solution' there. You really need to see a doctor if you find yourself 'lacking water' for some inexplicably reason.
