Thirty years time. A short time, when seen through the prism at 40.
Some political commentary, a little science & reviews on fast food and maybe a few songs! Got a problem with that? OK, so I'm an acquired taste...

Preserving two videos this night. Video #1: https://youtu.be/VCpTmMPWg94
Have patients - a play on words! This link still worked. Other songs are now diverted to ads... only ads - I'm not even sure how long this video will last. Who's doing this shit? I haven't a clue, except to say that even as a country that was sinking beneath the waves would still have crud companies like State Farm trying to sell us insurance. And just before our collective lungs filled with water, they would ask us if we liked their ad.... Insanity

Coronavirus Covid-19 clinical information!
Coronavirus clinical:
- COVID-19 is the disease, SARS-2-CoV is the virus.
- Transmission
- Respiratory and likely by fomite (contact with hard surfaces). Virus found in respiratory secretions and saliva.
- Stool shedding also described, but uncertain what role, if any, that plays.
- Incubation period
- Mean of 6.4 days, range 2-12. For people quarantined, 14d observation recommended to exclude infection, though 24d asymptomatic time from exposure described.
- Viral shedding occurs following recovery, but unclear what role this plays in transmission.
- Children and intrafamilial (family) spread appear to be a growing means of transmission.
- Cause of upper respiratory tract disease and pneumonia.
- The most common symptoms include fever, fatigue, and dry cough.
- Fever (83-98%)
- Cough (46-82%, usually dry)
- Myalgia (muscle pain) or fatigue (11-44%)
- Shortness of breath at onset (31%)
- Less common symptoms:
- Pharyngitis (inflammation of the pharynx )
- Headache
- Productive cough
- GI symptoms
- Hemoptysis (coughing up of blood )
- Estimates are ~80% of infections non-severe, including asymptomatic infection likely.
- The mortality rate is thought to be ≤2%, but precise numbers uncertain due to a lack of available serological testing.
- The mortality rate is less than that commonly ascribed to severe community-acquired pneumonia (12-15%) but more than seasonal influenza (~0.1%).
- Most deaths in patients with comorbidities (the simultaneous presence of two chronic diseases or conditions in a patient) and often elderly (> 60 considered a "risk factor"), although healthy younger patients also described.
- Epidemiology
- China remains with most reported cases, but as of March 2020, upswing in many countries including especially S Korea, Italy, US (California, Washington state).
NIH - Some coronavirus facts!
In late December 2019, the World Health Organization declared
the illness resulting from the new virus, COVID-19, a Public Health
Emergency of International Concern. By early March 2020, the novel
coronavirus—now named SARS-CoV-2—had infected more than 90,000
people worldwide and killed at least 3,100.Note: COVID-19 is the disease, SARS-2-CoV is the virus.
Like other coronaviruses, SARS-CoV-2
particles are spherical and have proteins called spikes
protruding from their surface. These spikes latch onto human cells,
then undergo a structural change that allows the viral membrane to
fuse with the cell membrane. The viral genes can then enter the host
cell to be copied, producing more viruses. Recent work shows that,
like the virus that caused the 2002 SARS outbreak, SARS-CoV-2 spikes
bind to receptors on the human cell surface called
angiotensin-converting enzyme 2 (ACE2).
The researchers found that the
SARS-CoV-2 spike was 10 to 20 times more likely to bind ACE2
on human cells than the spike from the SARS virus from 2002. This may
enable SARS-CoV-2 to spread more easily from person to person than
the earlier virus.
Despite similarities in sequence and
structure between the spikes of the two viruses, three different
antibodies against the 2002 SARS virus could not successfully bind to
the SARS-CoV-2 spike protein. This suggests that potential vaccine
and antibody-based treatment strategies will need to be unique
to the new virus.[It also suggest that more 'novel' mutations may occur in the future.]

Origin and evolution of pathogenic coronaviruses!
Severe acute respiratory syndrome
coronavirus (SARS-CoV) and Middle East respiratory syndrome
coronavirus (MERS-CoV) are two highly transmissible and pathogenic
viruses that emerged in humans at the beginning of the 21st century.
Both viruses likely originated in bats, and genetically diverse
coronaviruses that are related to SARS-CoV and MERS-CoV were
discovered in bats worldwide. In this review, we summarize the
current knowledge on the origin and evolution of these two pathogenic
coronaviruses and discuss their receptor usage; we also highlight the
diversity and potential of spillover of bat-borne coronaviruses, as
evidenced by the recent spillover of swine acute diarrhea syndrome
coronavirus (SADS-CoV) to pigs.
INTRODUCTION
Coronaviruses cause respiratory and intestinal infections in animals
and humans1.
They were not considered to be highly pathogenic to humans
until the outbreak of severe
acute respiratory syndrome (SARS) in 2002 and 2003 in Guangdong
province, China, as the coronaviruses that circulated before that
time in humans mostly caused mild infections in
immunocompetent people. Ten years after SARS, another highly
pathogenic coronavirus, Middle East respiratory syndrome coronavirus
(MERS-CoV) emerged in Middle Eastern countries. SARS coronavirus
(SARS-CoV) uses angiotensin-converting enzyme 2 (ACE2) as a receptor
and primarily infects ciliated bronchial epithelial cells and type
II pneumocytes, whereas MERS-CoV uses dipeptidyl peptidase 4
(DPP4; also known as CD26) as a receptor and infects unciliated
bronchial epithelial cells and type II pneumocytes. SARS-CoV and
MERS-CoV were transmitted directly to humans from market civets
(see More
Chinese push to end wildlife markets) and dromedary camels,
respectively, and both viruses are thought to have originated in
bats.
Extensive studies of these two
important coronaviruses have not only led to a better understanding
of coronavirus biology but have also been driving coronavirus
discovery in bats globally. In this review, we focus on the origin
and evolution of SARS-CoV and MERS-CoV. Specifically, we emphasize
the ecological distribution, genetic diversity, interspecies
transmission and potential for pathogenesis of SARS-related
coronaviruses (SARSr-CoVs) and MERS-related coronaviruses
(MERSr-CoVs) found in bats, as this information can help prepare
countermeasures against future spillover and pathogenic infections in
humans with novel coronaviruses.
CORONAVIRUS DIVERSITY
Coronaviruses are members of the subfamily Coronavirinae in
the family Coronaviridae and the order Nidovirales
(International Committee on Taxonomy of Viruses). This subfamily
consists of four genera — Alphacoronavirus, Betacoronavirus,
Gammacoronavirus and Deltacoronavirus — on the basis
of their phylogenetic relationships and genomic structures (Fig.
1).
The alphacoronaviruses and betacoronaviruses infect only mammals. The
gammacoronaviruses and deltacoronaviruses infect birds, but some of
them can also infect mammals. Alphacoronaviruses and
betacoronaviruses usually cause respiratory illness in humans and
gastroenteritis in animals. The two highly pathogenic viruses,
SARS-CoV and MERS-CoV, cause severe respiratory syndrome in humans,
and the other four human coronaviruses (HCoV-NL63, HCoV-229E,
HCoV-OC43 and HKU1) induce only mild upper respiratory diseases in
immunocompetent hosts, although some of them can cause severe
infections in infants, young children and elderly individuals.
Alphacoronaviruses and betacoronaviruses can pose a heavy disease
burden on livestock; these viruses include porcine transmissible
gastroenteritis virus, porcine enteric diarrhea virus (PEDV) and the
recently emerged swine acute diarrhea syndrome coronavirus
(SADS-CoV)34.
On the basis of current sequence databases, all human coronaviruses
have animal origins: SARS-CoV, MERS-CoV, HCoV-NL63 and HCoV-229E are
considered to have originated in bats; HCoV-OC43 and HKU1 likely
originated from rodents. Domestic animals may have important roles as
intermediate hosts that enable virus transmission from natural hosts
to humans. In addition, domestic animals themselves can suffer
disease caused by bat-borne or closely related coronaviruses: genomic
sequences highly similar to PEDV were detected in bats, and SADS-CoV
is a recent spillover from bats to pigs (Fig. 2).
Currently, 7 of 11 ICTV-assigned
Alphacoronavirus species and 4 of 9 Betacoronavirus
species were identified only in bats (Fig. 3).
Thus, bats are likely the major natural reservoirs of
alphacoronaviruses and betacoronaviruses.

The Horse-Burger. Has he lost his mind?
OK. I'll save everyone the suspense.
I have been adjudged, by a panel of psychiatrists (aka nut
doctors), as a 'marginal' individual on the basis of mental stability. That said, I'm still loose out in
society, have a spatula and am considered somewhat dangerous only in the kitchen! Disclaimer: No actual horse meat was used in the making of this meal!
----------------------------------------
My current 'Old Man Styled American Diet' (COMSAD), while not expressly
allowing for comfort foods such as hamburgers, did not specifically exclude them
either! To that end, I made myself up a very simple burger with just one small
twist. I added some horseradish to the duo of ketchup and mustard
that I normally apply. I called it a Horse-Burger, as a result. (It's
a free speech thing).
So, I had me two Ball Park buns, a hamburger patty,
a slice of onion and the aforementioned trio of condiments. Simple. (Much like
the cook)! Preparation was a breeze, as I cooked the burger on a 20 year
old Joe Foreman grill, that was working better than I was. The whole affair took about ten minutes, start to finish. I also added a dollop of Reser's coleslaw to the plate, right next to the burger and then sat down to dig right in....
RESULTS: In what might be described as 'youthful enthusiasm' (?), I used perhaps a tad too much horseradish! [One good side effect - My sinuses cleared up for the first time in quite a while!]
All that said, the Horse-Burger was pretty darn good and tasty! I do plan to make it again!
The total cost of this meal a deal was just about a buck. Contrast that to an order of a Big Mac with medium fries at close to $8!! Below is a fairly accurate estimate of the nutritional values:
