Yes, I know I promised a lengthy lecture on Fed Chairman Paul Volker and the slaying of the Inflation Dragon. Well, given the horrible condition the I have been in the past 72 hours, the ballad of Sir Paul and his Gallant Knights will have to wait. Well, that and it is Groundhog Day so there really shouldn’t be any lectures anyway…


See if you can guess what I did the last 72 hours?


From Wiki (checked)


The norovirus was originally named the “Norwalk agent” after Norwalk, Ohio, in the United States, where an outbreak of acute gastroenteritis occurred among children at Bronson Elementary School in November 1968. In 1972, electron microscopy on stored human stool samples identified a virus, which was given the name “Norwalk virus.” Numerous outbreaks with similar symptoms have been reported since. The cloning and sequencing of the Norwalk virus genome showed that these viruses have a genomic organization consistent with viruses belonging to the family Caliciviridae.[56] The name was shortened to “norovirus” after being identified in a number of outbreaks on cruise ships and receiving attention throughout the United States. The name “norovirus” (Norovirus for the genus) was approved by the International Committee on Taxonomy of Viruses (ICTV) in 2002.[57]

In addition to “Norwalk agent” and “Norwalk virus,” the virus previously has been called “Norwalk-like virus,” “small, round-structured viruses” (SRSVs), and “Snow Mountain virus.”[59] Common names of the illness caused by noroviruses still in use include “winter vomiting disease,”[60] “winter vomiting bug,”[61][62] “viral gastroenteritis,” and “acute nonbacterial gastroenteritis.”[2] It also colloquially is known as “stomach flu,” but this actually is a broad name that refers to gastric inflammation caused by a range of viruses and bacteria.

Noroviruses are a genetically diverse group of single-stranded RNA, non-envelopedviruses in the Caliciviridae family.[1] The viruses are transmitted by fecally-contaminated food or water; by person-to-person contact;[2] and via aerosolization of the virus and subsequent contamination of surfaces.[3] Noroviruses are the most common cause of viral gastroenteritis in humans,[4] and affect people of all ages.[4]

Norovirus infection is characterized by nausea, forceful vomiting, watery diarrhea, and abdominal pain, and in some cases, loss of taste. General lethargy, weakness, muscle aches, headache, coughs, and low-grade fever may occur. The disease is usually self-limiting, and severe illness is rare. A small number of people die, mostly the very young, the elderly, and persons with weakened immune systems.

Winter vomiting bug is a common term for noroviruses in the UK, because the virus tends to cause vomiting and to spread more easily in winter, when people tend to spend more time indoors and near to each other.[5]

After infection, immunity to norovirus is usually incomplete and temporary.[6] Outbreaks of norovirus infection often occur in closed or semiclosed communities, such as long-term care facilities, overnight camps, hospitals, prisons, dormitories, and cruise ships, where the infection spreads very rapidly either by person-to-person transmission or through contaminated food.[7] Many norovirus outbreaks have been traced to food that was handled by one infected person.[8]

Norovirus is rapidly inactivated by either sufficient heating or by chlorine-based disinfectants, but the virus is less susceptible to alcohols and detergents, as it does not have a lipidenvelope.[9]

The genus name Norovirus is derived from Norwalk virus, which causes approximately 90% of epidemic nonbacterial outbreaks of gastroenteritis around the world,[10] and may be responsible for 50% of all foodborne outbreaks of gastroenteritis in the United States.[11][12]

‘General lethargy’ is a fine description of where I am now.

Of course, prevention is key:

Stop the Spread of Norovirus

Photo: Washing hands with soap and water.Practice proper hand hygiene

Wash your hands carefully with soap and water, especially after using the toilet and changing diapers and always before eating or preparing food. If soap and water aren’t available, use an alcohol-based hand sanitizer. These alcohol-based products can quickly reduce the number of germs on hands in some situations, but they are not a substitute for washing with soap and water.

Take care in the kitchen

Carefully wash fruits and vegetables, and cook oysters and other shellfish thoroughly before eating them.

Do not prepare food while infected

People with norovirus illness should not prepare food for others while they have symptoms and for 3 days after they recover from their illness. (see For Food Handlers: Norovirus and Working with Food)

Clean and disinfect contaminated surfaces

After throwing up or having diarrhea, immediately clean and disinfect contaminated surfaces by using a bleach-based household cleaner as directed on the product label. If no such cleaning product is available, you can use a solution made with 5 tablespoons to 1.5 cups of household bleach per 1 gallon of water.

Wash laundry thoroughly

Immediately remove and wash clothing or linens that may be contaminated with vomit or stool. Handle soiled items carefully—without agitating them—to avoid spreading virus. If available, wear rubber or disposable gloves while handling soiled clothing or linens and wash your hands after handling. The items should be washed with detergent at the maximum available cycle length and then machine dried.

    One note of caution on those alcohol-based gel hand sanitizers… For those who don’t know, many of those products are essentially related to napalm in physical characteristics – a gelled flamable agent. Useful, no doubt, but keep that in mind and keep them (and you, when using them) away from open flame or anything else capable of igniting them. You’d be better off getting sick than having 2nd or 3rd degree burns on parts of your anatomy. Test your preferred brand by putting some on a safe surface and setting a match to it, and tailor your precautions according to the results.

    Passing through, but caught this tid bit over at PJ Media

    Declare the NRA a terrorist organization and make membership illegal. Hey! We did it to the Communist Party, and the NRA has led to the deaths of more of us than American Commies ever did. (I would also raze the organization’s headquarters, clear the rubble and salt the earth, but that’s optional.) Make ownership of unlicensed assault rifles a felony. If some people refused to give up their guns, that “prying the guns from their cold, dead hands” thing works for me.

    Whipping up hate and violence. How progressive.

    Twitter is not happy with Chris Matthews tonight after the MSNBC anchor concluded that Sen. John McCain’s tough questioning of former colleague Chuck Hagel yesterday originated in “the deep well of resentment burning in John McCain’s patriotic heart.” What? “I’m absolutely convinced we’re watching a flashback,” said Matthews upon introducing a clip of McCain addressing Hagel.

    Matthews is impossible to under estimate.

    @ Buckeye Abroad:

    Specifying “American” commies is a nice touch, but false. There was never any difference between American Communists and the Soviet Union. The CPUSA was a wholly-owned subsidiary of the USSR.

    Today, it’s morphed into the Democratic Socialists of America (DSA) which currently controls the Democratic Party at the national level.

    In other words, today’s Democrats are basically agents of international Communism, which killed hundreds of millions of people in the 20th century.

    That’s the group that should be outlawed and its leadership jailed.

    Obama Blames Economy on ‘Bad Decisions’
    9:49 AM, FEB 2, 2013 • BY DANIEL HALPER Single PagePrintLarger TextSmaller TextAlerts
    In his weekly address, President Barack Obama blamed the economic problems on “bad decisions.”

    “[T]his week, we also received the first estimate of America’s economic growth over the last few months. And it reminded us that bad decisions in Washington can get in the way of our economic progress,” said Obama, presumably referring to the uptick in unemployment from 7.8 percent to 7.9 percent and the news that the economy contracted in the final quarter of last year.

    You can bet that he was not saying that any of the bad decisions were his.

    That’s a little far aft for a muzzle brake, don’t you think? Besides, who the hell puts a muzzle brake on an OU shotgun? And how would you even do such a thing? Or want to?

    That photo has been doctored…

    @ coldwarrior:

    Maybe so, do they port over/unders? This one appears to be ported in only one place rather than around the barrel, so i suppose it could be to prevent muzzle climb. Also trying to figure out the white item coming out of the top barrel. Can’t be the wad because there is smoke forward of the barrel and in front of the white object, so one would expect that the wad and shot are long gone.

  20. 20 | February 2, 2013 11:35 am

    @ AZfederalist:

    It’s bullshit. The object forward on the upper barrel is an insertable choke, which appears to be in the path of shot from the lower barrel. The plume of gas from aft on the upper barrel is to far aft to work worth a crap and appears to be venting from the side in any case – not exactly a help keeping on target. Color me extremely dubious…

    That’s not an expensive skeet gun – it’s a fake photo based on a skeet/trap/hunting gun.

    22 | February 2, 2013 11:43 am

    @ Mike C.:

    Looking at the original size photo, it does appear to be ported with the exhaust gas in the correct place. I guess I see that could be an insert able choke, but why isn’t there a similar one on the bottom barrel?

  23. 23 | February 2, 2013 11:46 am

    @ Mike C.:

    I suppose it could be a real shotgun, provided it was something cobbled up by some moron. If anybody need to see what expensive skeet guns look like in action, watch this…


  24. 24 | February 2, 2013 11:48 am

    @ AZfederalist:

    It’s poorly-concocted bullshit. Good skeet guns don’t have variable chokes that would look embarrassing on a Mossberg pump action. They also don’t have muzzle brakes/compensators.

    I’m perfectly willing to allow people to think it’s real.

    Whatever it is, I think it’s a mistake from Team Soetoro.

    The people whose minds are somehow not made up on this issue tend to poll more pro-Second Amendment than anti-, and I believe that this will only serve to swing them in the direction of less device restriction.

    It will also chafe the hineys of the true-believer outright gun ban folks.

    Take a look at the original size picture

    Looks like venting on the barrels and that is not a choke on the end of the barrel. Somebody elsewhere opined that he is shooting a blank. That would explain the exhaust gas in front of the wad coming out of the barrel. That wouldn’t be the case with a real round.
