That's true, but probably not to the extent most would think, mostly you just have to put more effort into activities that are productive and less into activities that are non-productive. About 20% of your activity is going to produce 80% of your results, so you hire assistants to do the 80% and you consentrate on the 20% of that that is making 80% of your money and do more of it.

Hughesnet Gen4, 10 Gb anytime, 10Gb from 02:00-08:00, it's pretty hard to not hit the cap for me. No DSL possible, they'd have to replace the telephone line from the DSLAM to the house, comcast just laughes. Our electricity comes in single phase, we don't even have cross beams on the power poles, just hot and neutral one above the other. OBTW I am in the US, not Afganistan or Hati.

The only rational reason that ACA exisists is to make Insurance-funded heathcare so bad that a socialized single payer system looks better in comparison. Under US law, Income taxes are specifically excluded from discharge via bankruptcy proceedings so we've gone from a system where people were forced into bankruptcy for medical expenses, to a system where even bankruptcy will not save you from your medical expenses and if for any reason the IRS finds that your subsidy was in error, they will not only required repayment, but tack on penalties (which are typically the amount to be repayed) and interest.

Research suggests that blind people are superior to sighted in echolocation, but systematic psychoacoustic studies on environmental conditions such as distance to objects, signal duration, and reverberation are lacking. Therefore, two experiments were conducted. Noise bursts of 5, 50, or 500 ms were reproduced by a loudspeaker on an artificial manikin in an ordinary room and in an anechoic chamber. The manikin recorded the sounds binaurally in the presence and absence of a reflecting 1.5-mm thick aluminium disk, 0.5 m in diameter, placed in front, at distances of 0.5 to 5 m. These recordings were later presented to ten visually handicapped and ten sighted people, 30-62 years old, using a 2AFC paradigm with feedback. The task was to detect which of two sounds that contained the reflecting object. The blind performed better than the sighted participants. All performed well with the object at 2 m was not by chance. Detection thresholds showed that blind participants could detect the object at longer distances in the conference room than in the anechoic chamber, when using the longer-duration sounds and also as compared to the sighted people. Audiometric tests suggest that equal hearing in both ears is important for echolocation. Possible echolocation mechanisms are discussed. Human echolocation: Blind and sighted persons' ability to detect sounds recorded in the presence of a reflecting object.

I would certainly suspect that a non-sighted person who echo-locates would be far better than a sighted person, if for no other reason than getting much more practice, I would be interested in comparing a non-sighted and sighted echo-locator in a similar investigation. Could be that that part of the visual cortex could be used in both eyesighted and earsighted vision to varying degrees.

I'm seeing a lot of no-till and low-till farming in my area, now the large-scale crop farmers are using precise soil testing and only using the amount of artificial fertilizers absolutely necessary. A lot of what your saying is standard practises have went out of style in the late '70s.

No actually anyone can supposedly do it,

A study of sighted people newly trained to echolocate now suggests that the secret to Kish’s skill isn’t just supersensitive ears. Instead, the entire body, neck, and head are key to “seeing” with sound—an insight that could assist blind people learning the skill. ... Although some people are more naturally talented than others at echolocation, most got “quite good” after 2 to 3 weeks of training, Wiegrebe says, and could reliably orient themselves to walk down the corridor without running into any walls using just clicks and echoes.How blind people use batlike sonar

does seem like they learned to do it about twice as fast as I've seen reported elsewhere too.

350,000 curies x 0.0114 gram Cs-137/curie = 3980 grams (4 kg) – of Cs-137. It decays by beta emission which in water is quickly absorbed; typically within 10mm - 15mm.

But don't let a good scare story go to waste.

Which means if you eat or drink the stuff, the radiation is totally absorbed by your tissues, unlike Gamma radiation that for the most part goes through you like light through glass.
