Oral Rehydration Therapy. The preferred version is slightly more complex; but it's pretty much a sugar/salt solution in water, designed to replenish lost fluids without causing electrolyte issues if consumed in large quantities. Cheap and easy to do without much equipment or medical expertise.

You crazy end-times nutjobs... Everyone knows that Verichip(tm) brand subdermal RFID solutions are supposed to be implanted in the arm, not the hand or forehead!

It's pretty tricky to avoid the 'carry something around' requirement; but people seem to be good enough at that when they need to be.

I suppose the major mess would be all the phones and tablets that either don't have card readers or USB, or have USB but will never receive driver support outside of third party hacks. Smartcards and their USB attached analogs can handle the job but having accounts that you can't access from almost any mobile device will probably play poorly.

It does have that (though using a stylus still tends to involve enough contact with your hand to make cleaning relevant); but it is also a touchscreen device so depending on the don't touch it school of cleanliness is a bit of a waste.

Do they have matte screens that can handle having disgusting human finger grease smeared on them?

The glossy ones collect it; but at least can be wiped off. Getting fingerprints off matte screens tends to be more obnoxious.

I'm not sure that the incentives line up in this case: Alzeimer's tends to be expensive because of the amount of care and nursing people require as their cognitive state declines; but the pharmaceutical options are sparse. People would beat down your door for the chance to pay for pills what they now pay for nursing if you had something(even if it has to be taken twice daily forever) that was suitably effective. Anyone who could would likely pay more because the disease itself is so nasty. Seems like a very lucrative position for anyone except those currently doing the nursing.

On the plus side, if you are truly tacticool, the sheer mass of black-anodized widgets rail mounted to your gun will offer substantial stability improvements during fire..

It's not as nice as a sanitation system good enough to prevent the problem; but ORT is pretty good at keeping you from dying of it and a great deal cheaper.

There's also the fact that a fancy scope system designed to improve accuracy against relatively distant targets likely isn't worth the weight, much less the cost, for use indoors at very close range.

It's possible that there are some would-be snipers out there, currently restrained only by incompetence; but barring those this system isn't of obvious interest for most spree killing purposes.

It makes a lot more sense if you think of ornamental landscaping (and much of fashion in general) in terms of competitive display rather than pursuit of some specific aesthetic ideal. It is precisely because something is pointless and relatively resource intensive that it is a good competitive display. If it were purely utilitarian, or if it were trivial, everyone would have one. Lawns are also good for this because deficiencies in maintenance become publicly visible, in the form of various 'weeds' and irregularities of color or height, fairly quickly.

Unless the OR is pain waiting to happen for users with ordinary vision I'd imagine that the optics are designed to provide a comfortable apparent distance from the screen for viewers with ordinary eyesight. This would mean that a nearsighted user would still be attempting to focus on something that appears further away than close-in vision is suitable for.

Somebody comfortable at closer distances would likely require slightly less correction from the internal optics, since their comfortable apparent distance is shorter; but if the optics aren't designed that way that doesn't help them very much.

Unless your proposal involves turning the old people into soylent grey, there definitely is. It's a particularly slow and very, very, unpleasant way to die(not so much because of any gruesome physical symptoms as because gradual and relentless loss of assorted important congnitive functions is both terrifying and increasingly incomprehensible as you lose more of them) and makes the victim substantially dependent on caregivers some years before they otherwise might be. Very hard on the patient, very hard on their relatives, and quite expensive, often for a number of years.

Based on the concentration of government and defense contracting in Virginia, I'm going to guess that the slowpokes from Virginia had to finish intercepting and storing your traffic before they could waste time on the internet and generate theirs...

If the Americans are too expensive why would you enter a clandestine agreement to keep recruiters away from yours? Wouldn't you want the overpriced guy to be somebody else's problem? On the other side, why would your competitor be willing to offer a higher salary than you do if you are already paying too much?

This sort of agreement (especially given the legal risk involved) just wouldn't make much sense if you thought that the employees in question were already overpriced.

There's also the difficulty of what counts as 'a zero day' for purchasing purposes. An unpatched exploit in any software? Do I need X thousand installs? Are just five enough, if they are paying a lot for it? How do we tally users of other things that are indirectly related to the issue?

People buying them to weaponize them have a fairly straightforward set of incentives(which may vary depending on what they are looking to access, whether they are after money or information, and so on). People looking to buy them for disclosure don't get the same, because virtually any exploit on the market is theoretically within that goal; but actually establishing the value of a specific one is harder unless you go down the troublesome road of defining your priorities(in terms of what systems, users, and activities you consider more or less high priority when assigning a value to exploits that would affect them).

If you are selling dangerous ones, to be used, you'll have some trouble getting repeat customers if your stuff is nonsense or works on things that aren't worth attacking. If you are selling to someone with a 'buy up the exploits' mandate you potentially have much more flexibility to haggle over stuff you more dangerous buyers aren't interested in. In the same vein, various vendors, users, and organizations would be inclined to try to lobby their way up the priority list in order to score an outside QA team.

There are likely some unambiguous cases; but telling the spooks 'do what you think best' is obviously a terrible plan, while trying to codify a reliable and unambiguous set of criteria to be followed seems quite difficult and prone to influence.
