Look at who is spending that money on healthcare. Almost all of it is the elderly and people with chronic conditions receiving treatments aimed at preservation (even the words we use: "cure" rather than "heal" reflect this) that may or may not even be effective at achieving this lesser goal. The emergency room scenario is less than a drop in the bucket and really has no place in discussions about the cost of healthcare.

It certainly appears that "they" have inflated the currency to save the banking system thus wiping out large chunks of the older generations savings. To prevent outrage about this, they are now forcing young people to purchase health insurance they don't need to subsidize the healthcare of their parents/grandparents who would no longer be able to afford it otherwise. It has been sold all the way as a "human right" by conflating health insurance with health care and health care with health.

Buying health insurance was always a scam for young people (under 45), they would be much better off having that money put in a savings account each month rather than gambling against themselves with the insurance companies where the money is gone from the people who will need it later (but goes towards "stimulating the economy" and tax revenues). Now it is just that the system is too big to fail so everyone needs to be forced to participate.

I'd be interested to know if anyone can spot something that would make this simulation invalid in the case of 2012 DA14. I just searched through and copy-pasted excerpts containing the word assumption for effect, but have no idea how important any of these are:

"To implement such a program, it is necessary to make some simplifying assumptions that limit the accuracy of any predictions."

assuming that the meteoroid is approximately spherical

For the purposes of the Earth Impact Effects Program, we
assume that the trajectory of the impactor is a straight line
from the top of the atmosphere to the surface, sloping at a
constant angle to the horizon given by the user. Acceleration
of the impactor by the Earthâ(TM)s gravity is ignored, as is
deviation of the trajectory toward the vertical in the case that
terminal velocity is reached, as it may be for small impactors.
The curvature of the Earth is also ignored. The atmosphere is
assumed to be purely exponential:

We define the airburst altitude zb to be the height above the surface at which the impactor diameter L(z)
= 7L0. All the impact energy is assumed to be deposited at this altitude;

if the unbulked breccia lens volume Vbr (i.e., the observed
volume of the breccia lens multiplied by a 90â"95% bulking
correction factor; Grieve and Garvin 1984) is assumed to be
related to the final crater diameter by: Vbr â 0.032Dfr^3

Assuming that the top
surface of the breccia lens is parabolic and that the
brecciation process increases the bulk volume of this
material by 10%

we assume, based on numerical modeling work
(Pierazzo and Melosh 2000; Ivanov and Artemieva 2002), that
the volume of impact melt is roughly proportional to the
volume of the transient crater

Here we assume that the
crater floor diameter is similar to the transient crater diameter

Numerical simulations of vapor
plume expansion (Melosh et al. 1993; Nemtchinov et al. 1998)
predict that the fireball radius at the time of maximum radiation
is 10â"15 times the impactor diameter. We use a value of 13 and
assume âoeyield scalingâ applies to derive a relationship between
impact energy E in joules and the fireball radius in meters

The time at which thermal radiation is at a maximum Tt is
estimated by assuming that the initial expansion of the fireball
occurs at approximately the same velocity as the impact:

for a first-order estimate we
assume Î = 3 Ã-- 10â'3 and ignore the poorly-constrained
velocity dependence.

âoeas a rough approximation, the amount of thermal energy
received at a given distance from a nuclear explosion may be
assumed to be independent of the visibility.â

To calculate the seismic magnitude of an impact event,
we assume that the âoeseismic efficiencyâ (the fraction of the
kinetic energy of the impact that ends up as seismic wave
energy) is one part in ten thousand

we assume that the main seismic wave energy is that
associated with the surface waves.

For simplicity, we ignore the uplifted fraction of the
crater rim material. We estimate the thickness of ejecta at a
given distance from an impact by assuming that the material
lying above the pre-impact ground surface is entirely ejecta,
that it has a maximum thickness te = htr at the transient crater
rim, and that it falls off as one over the distance from the
crater rim cubed

we
assume that the transient crater is a paraboloid with a depth to
diameter ratio of 1:2

assumes that all ejecta is thrown out of the crater from
the same point and at the same angle (45Â) to the horizontal.

we assume that the impact-generated shock wave in
the air is directly analogous to that generated by an explosive
charge detonated at the ground surface

the Mach region is
assumed to begin at the impact point

For convenience, however, we assume that the shock
wave travels at the ambient sound speed in air

The air blast model we use extrapolates from data
recorded after a very small explosion (in impact cratering
terms) in which the atmosphere may be treated as being of
uniform density. Furthermore, at this scale of explosion, the
peak overpressure decays to zero at distances so small (

I expected this response because you are too uneducated to predict that I knew you would qualify your statement and fail to interpret my purpose in saying that. Now go look up who has ever said that the process of science has proved something. If you come back with more nonsense thats the end of my attempt to help you understand science, but hopefully the seed has been planted.

If you think our current theories of the origin of life are factual you are misled. How the hell should people know for sure what happened billions of years ago or even that it was billions of years ago? There are just more and less plausible theories that get selected from based on when a few compete and one turns out to be more useful than the other. The people advocating science really need to learn what it is. I don't believe in god btw (thats not to say something like that can't exist).

Lateral thinking shows that if Man is just another process of the Universe, then if you PLACE each die in the SIX position, it is the same conceptual process as rolling the die, and this being so you can place any number of dice in the SIX position.

Do the experiment. You claim you can place "any number" of dice in the six position. See how many is actually possible to maintain in the six position at once. Its also absurd to consider placing as the same thing as rolling/throwing when you encounter that these two activities are different in some way probably every day of your life... but I would encourage you to do the actual experiment of seeing how many you can place with the six facing up before something disrupts the order you have created.
