Re: EU: Bird Flu Pandemic Would Be Akin To Major Recession

Boccaccio, nice first-hand discussion about people failing to leave New Orleans before Katrina . . . "they chose to stay". Implicit in that choice to stay was an assumption that "bad things won't happen to me".
I think that this same assumption is what hampers people from preparing for a possible pandemic. An H5N1 pandemic will spread relatively quickly, but not all areas will be affected at the same time. It will be an interesting phenomenon to see how local populations and communities react based on a perceived threat even if H5N1 is not yet within the local community.
I agree that most people simply don't think bad things will happen. And bad things mostly don't, actually. Even here in earthquake country, the vast majority of people were essentially utterly unaffected by the last two major quakes, Loma Prieta and Northridge. In both areas, one had to go to damaged areas to "gawk" at the collapsed apartment buildings, the fire damage to the Marina District, etc. Of course, in both quakes there were collapsed freeway structures and overpasses, which affected traffic for months or longer. And condemned buildings, which forced relocations. But these were, importantly for the point, things which did not directly mean people should have "prepared"--the loss of the Cypress Structure in Oakland was not something people could prepare for, individually.
There's something in being a "prepper" (a term favored on some of these bird flu groups or boards) that is akin to being a "survivalist" (a term not favored here, and one which can rightly suggest someone moving off to the wilds of Oregon to live a mountain man life, with guns....not all survivalists are this extreme, of course).
An old girlfriend of mine, who's a licensed psychologist/therapist, once characterized me as being "hypervigilant." I later Googled this term and found some parts of the definition which are true of me.
(Not that I am hypervigilant, or even especially wise, in all matters! Amongst other things, I don't go to doctors, ever. A failing on my part, I acknowledge. Something I keep planning to change....)
On things related to preparing for the future, I think I'm indeed pretty vigilant, even hypervigilant. I've cringed to see my neighbors now responsible for maintaining our water (a well and tank, serving our hill, with 15 households) continue to "not think ahead" and to just let things deteriorate. They thought I was "weird" (one of their words, not mine) when I asked technical questions about the size of the pump, etc., as an explanation of why the main tank was running dry so often (with implications for our water, for fire reasons, and even for our homeowners insurance policies!).
(For those interested in the details, as a snapshot of how a "prepper" mentality can affect such a real-world situation, here's a snapshot of the situation and the outcome. Lack of pictures and a lot more words than I'm prepared to type may make it hard to grasp the explanation, but I'll try.
Basically, we have a deep well from which is water is pumped to the surface and then up about 350 more feet to a storage tank at the top of the hill. From there it is gravity-fed to the lower households. The houses up near the top need local pressure systems to raise the pressure to normal levels (about 50 PSI). Several years ago the water committee listened to a vendor who said that a less expensive pump would make a good replacement for the 10 horsepower, 3-phase electricity, 18-stage pump that had been installed in 1972 and then replaced later with a pump of the same specs. (I don't have space to tell you all what "stages" are in a pump, except that they're how a pump can pump more than just one "suck" on a straw (if one sucks on a straw or hose or pipe, the most that can ever be sucked is equivalent to about 30 inches of mercury or 33 feet of water....this is just basic physics. Pumps use multiple stages to pump water to greater heights.)
The replacement pump several years ago was a 7.5 horsepower, single-phase, 13-stage pump. None of this was ever publicized to the rest of us (I had been head of the water committee several years earlier), none of it was described in the minutes of meetings, etc.
Anyway, we had three years of inadequate water flow, including occasional emptying of the storage tank (which is very bad news, for multiple reasons, even including bacterial problems due to back-siphoning). The water committe and "leadership" (President of the Water Association) exhorted us to "use less water" and rigorous irrigation and water sprinkling schedules were mailed around. This went on for two years after the problems first hit big time.
A consultant was hired, he said he was "looking for leaks, where the water must be going" (the assumption being that water was leaking off someplace, though a simple calculation showed that there would have been some mighty big "wet spots" if this amount of water were leaking away). The consultant found no leaks, wished us good luck, and was paid.
And so on. So in the summer of 2004, after a spate of tank emptyings and more "we have to conserve water!" letters sent out, I brushed off my hypervigilant thinking cap and went out and did the following"
-- I walked the hill, top to bottom and back, nothing the locations of all faucets, pump locations, and elevations (using my GPS ETrex Legend to get elevations from the satellites...yet another example of where survivalist/camping supplies and tools are useful to have)
-- I took a satellite photo of the hill (from Mapquest, I think it was, though Google Earth is now a better choice) and marked the locations
-- from this, I knew the precise distance up the hill the water had to be pumped, and what this entailed for how many stages needed.
-- but was our pump adequate? Finding nothing in the minutes of what kind of pump we had, and phoning the President (of our Association) and him having no idea either, I dug through copies of the purchase orders and found something with some interesting numbers attached. Inputting the precise string of letters and numbers into Google, the hits I got showed the item was a Grundfos brand of pump, 7.5 horsepower, single-phase, 13-stage pump, rated for 60 gallons per minute. And 60 GPM was what we needed to meet fire and usage requirements, but a check of the GPM gauge at the wellhead only showed 14 GPM!
(To complicate things for readers here, we actually have two storage tanks, one lower than the other. Water is pumped first to the lower tank, and also used from there by some households, and then a second booster pump pushes some of this water to upper, main tank. All of these heights got measured and noted in my trek that day.)
-- checking further, and calculating the heights, it was obvious what was going on: a 13-stage pump is just "not enough pump" to pump water the requisite height, at least at anything more than a "gasping" level.
-- the answer was so clear and so obvious to any "hypervigilant" person (scientist, engineer, diagnostician like "Dr. House" on that great t.v. show) that I was stunned. Three hours of walking, measuring, calculating, and Web searching had revealed the solution: go back to the size of pump we USED to have and that had been specced by the designer of our hill's water delivery system back in 1972.
-- I wrote up my conclusions, attached the maps and calculations and even some explanations of "stages" and "hydrostatics" and the relevant equations, and sent copies to the Water Committee and the President.
-- deadening silence
-- when I asked the President, my immediate neighbor, what was going on, he shrugged and said they had been told by the pump vendor that the pump they'd had installed "was a 60 GPM" pump and that my calculations looked like garbage.
-- I felt like screaming at him: yes, 60 GPM, but only at the height relevant to that particular pump! The height in our system neeed a pump with more stages!
(As it happens, most deep water pumps come at various numbers of stages, usually ones in a few stages, in 8 stages, in 13 stages, in 18 stages, in 25 stages, and even some in more stages, for truly deep wells or high pumping distances.)
-- I asked him why he thought 13 stages was enough for our system....he drew a blank and said he'd get back to me. When he did, a week later, he said their paperwork showed they'd calculated the well depth to be 250 feet and the vendor had then told them the pump would be enough.
-- But, I reminded him, the water not only had to be brought to the surface, down at the bottom of the hill, but then pumped a further few hundred feet to the first storage tank. Another blank look.
-- He said he'd take my calculations to the next meeting of the Water Committee, scheduled in a few weeks.
-- Not believing me, nor my detailed calculations and equations, they contacted the water irrigation company that had sold them the pump. Apparently this company was only used to providing irrigation pumps, so they only calculated the pump needed based on getting the water up to the surface....this was all they knew.
-- So the light gradually dawned on them, or some of them.
-- A month later, another well pump company was consulted and my calculations were completely confirmed.
-- So the old pump was sold off for some slight credit, a new 18-stage pump with the 60 GPM capacity was installed, and we were all assessed the money needed to do this.
Two years later, there have been no repeats of the tank-emptying fiascos, the water situation is generally fine, and the silly warnings about how we all need to limit toilet flushes and sprinkler usage have all mysteriously ended.
They still think I'm "weird," mainly because the idea of doing calculations and measurements and not taking the word of an "expert" (who actually misunderstood our particular situation, and was unaware of pumping up hills issues) is alien to them. I could see their eyes glaze over as I verbally explained how water is pumped up hills, how height of a column of water translates to pressure, and hence to "stages" in a pump.
This is part of our innumerate society. And this is how small communities, small systems, are often just plain lacking in depth of knowledge. (Not that bigger systems or governments are necessarily better in all ways, but at least they don't have ill-prepared, unvigilant neighbors screwing up in such ways.)
This is one reason I try to be on good terms with my neighbors, but don't try to rely on them for my own needs.
(And don't get me started on our recent problems with the water failing bacteriological contamination tests....I know why, in all likelihood, and wrote them a report citing the reasons (backflow and siphoning from lawn soaker hoses, loose connections in the dirt, sprinkler systems resting in horse pastures, etc.) and they just have blank expressions...but they brought in a "consultant" who told them our system was subject to, drum roll, siphonage and backwash of contaminated water into the main pipes and tank!)
I apologize for this long detour, but you all were warned it was a detour. I beiieve this is a relevant story about preparations, calculations, and "vigilance" (thinking, reflecting, observing, measuring...) in ordinary situations.
Interestingly, on a computer group I sometimes post to, I described this adventure as an example of engineering innumeracy. The science fiction writer Neal Stephenson, of "Snow Crash" fame, commented that he thought this article could be expanded into a very nice piece in a major magazine about how these small community systems work, and how they fail, and how the inability of people to think about numbers and equations and diagrams has some very real implications for safety and expenses.
