New epidemics and basic hygiena
(Written in 2003, updated since)
Reccurent problems (Covid-19, SARS) remind us that new epidemics
(Corona Viruses, SARS, AIDS...)
could, at any time, cause million deaths (like the spanish
flu did) and even threaten the very survival of our civilization.
Science seems unable to prevent this, and genetics could even create
new risks. However free, simple and efficient solutions exist, here
and now, to block the propagation of epidemics, or at least to
significantly improve our chances of not being among the victims.
Covid19: after the WHO 5 994 000 people died for not reading this page (March 8, 2022). After a study in The Lancet, 18 200 000 died (counting the excess of mortality in 2020 and 2021). Still an effort, and you will reach 60 millions, as in 1918!

The problem today 2003
(Permalink)In 1918, the spanish flu killed 21 millions
peoples in the world. Every year, the «benign» flu claims
tens of thousands lives (20 000 in the USA) and keeps all of us stuck
in bed several weeks a year. The AIDS epidemics is now out of control,
even if it could be very simple to protect us. The recent SARS epidemics,
despites a contagion rate weaker that the flu (seemingly) provoked
a world wide psychosis, but this fear however did not incited much
people to take efficient steps.
Frequent travels and new ways of life cut off
nature, already strongly improved the odds for a new epidemics to spread
in the world in some weeks, see in some days. Worse, viruses and bacteria
mutate constantly, exchange gens, or suddenly wake up from natural reservoirs
where they were sleeping since millions years. There is thus a constant
risk of the appearance of new diseases, against which we would have
no immunity. At any moment, in some weeks, see in some days, an
unknown epidemic could sweep the world and take millions lives, disorganize
our societies, and even make our civilisations disappear.
Future could be still worse 2003
(Permalink)But the greatest dangers come
from the genetic sciences.
The point here is not to reject genetics, but
to be aware of some facts:
To create artificial viruses is a technics
used as a routine in public or private labs. The necessary technology
is within reach of a government, a rich person, or any great organization
(As seen with the Raël sect, technically and financially able
to try cloning). To create a new dangerous virus is within reach of
thousands of persons in the world. Some of these peoples could even be
unknown, or with very unexpected motives.
We immediatelly think to the biological
warfare, theoretically forbidden, but labs could easily continue
to work on it confidencially, on the command of governments, or
without their knowledge. Horrible collections of diseases exist,
hold by public organisms, by private firms, even sometimes by simple
individuals (Daan Goosen case, South Africa).
Certain politicians complacently added fuel
to the fear of anthrax or variola. In facts these diseases are not
very dangerous, as they do not propagate easily, and only in dreadful
hygiena conditions, happily disappeared of most countries.
But a real hazard comes from bacterias or
viruses which propagate easily, even in the mild hygiena conditions
which prevail in western countries, such as flu, cold, gastroenteritis,
which strike us every years.
TODAY (OR SOON) THOUSANDS OF PERSONS ARE
ABLE TO MODIFY THE VIRUSE OF THE ORDINARY FLU, TO ADD IT DANGEROUS
OR DEADLY GENES. IF SUCH A THING WOULD HAPPEN, THE MAJORITY OF THE
WORLD POPULATION COULD DISAPPEAR.
Fascist governments, rich nutters, terrorists
groups, sects, and even simple lab workers, could try to launch
deadly or disabling epidemics, or to do «jokes» such as
modifying benigne viruses to make them produce various substances
active on the human body and mind. Imagine what could be the results
of a viagra flu, or a LSD cold... Bacteria modified
by pharmaceutic compagnies could leak by accident (so they shall
leak). For instance escherishia coli producing insuline
would provoque a serious disease, contagious, and difficult to cure.
Besides such an accident, Tchernobyl would be just a gentle joke.
To speak clearly, we could face in some years
a situation similar to that of Internet, where each day could see
a new disease, in an enslessly series of parades and counter-attacks.
So there is really the need to a global
solution, which coult twart any epidemics from its very start,
whatever viruse is involved..
The false solutions 2003
Panic. To take violent or discriminatory steps against
people or groups who would be presented as «responsible»
of the disease, or against persons who would refuse useless or abusive
measures, or against people who would try to apply true solutions.
Secrecy. Certain governments, «Not to create a panic»,
or not to look unable, would try to hide the beginning of an epidemics
(SARS in China). But it is preciselly at the beginning that we can
efficiently gain control on an epidemics.
Waiting, or take delaying steps. In an epidemics, efficient
decisions are to be taken as soon as the first hours.
Abusive authority. Useless quarantines or travel restrictions
could have a human cost higher than the epidemics.
Abusive freedom. In the name of freedom, to allow for useless
and dangerous behaviours which spread the disease, or to refuse necessary
measures of isolation or hygiena. For instance AIDS spreaded through
sexual vagrancy, and it now maintains itself mainly with prostitution.
Certain fascist pressure groups made bear the blame to the society,
while at the same time increasing the standing of sexual vagrancy
behaviours which spread the disease. So the sexual freedon is now
in fact reduced. On the countrary a spiritual work on enhancing the
ability of living together would have both increased freedom while
reducing the occasions to spread the disease.
puritanism (added 2008) Some nutter religious groups
try to cast shame and censorship on diseases like AIDS, thus hampering the
prevention. Or they propose illusory solutions, such as «chastity
rings»... for women only! The most fascist try to make believe that
sexual mutilations such as circumcision or excision, would protect against AIDS!
This is of course pure psychiatric deliria.
To rely only on vaccines: To develop and test a vaccine requires
years, when an epidemics develops in only some days. Anyways,
more than one century of intensive searches had produced vaccines
only for a small percentage of deseases. Certain vaccines could
even have unacceptable noxious effects, which would be imposed even
to persons in good health. In these conditions, it appears illusory
to spend all the money and all the research effort on only the search
for vaccines, or to base prevention on only vaccines. It is criminal
to take no measures against a disease under the pretext that «we
shall find a vaccine»
Added March 2022: Thanks to the evolution of science, I have to soften the above, because today creating a vaccine takes only one year. Moreover the covid epidemic brought a real novelty: mRNA vaccines, which do not bring the dangers of classical DNA vaccines. Indeed, the RNA cannot penetrate our DNA, and it is expelled from the cells in some days.
The true solutions 2003
The terrific picture above just completelly evaporates if we consider
that, in facts, it is relativelly easy to protect ourselves against
the main sources of transmission active today: the transmission by
saliva, nose secretions, and somewhat also by excrements.
The basic principle of this transmission is simple: mucus or saliva
contain dangerous bacteria or viruses. Coughing, spluttering or sneezing
project fine infected particules in the air, that other persons will
breathe. To blow our nose, lick our fingers, and then touch objects,
infect these objects. This is the transmission mode of flus, colds,
gastroenteritis, childhood diseases, and numerous diarrhoeas.
In countries where there is no drinkable water, intestinal bacterias
can contaminate drinking water. But, even in western countries,
to wipe ourself in the toilets infects our hands, then the objects
we touch: if other persons touch these objects, then touch their mouth,
so he dangerous bacteria or virus get in them. This is the transmission
mode of cholera, of polyomyelitis and numerous other
Contagion happens with:
- To cough, sneeze, spluter, spit
- To shake our hands, kiss
- To blow our nose, then touch objects
- To use together the same glass, the same ustensils
- To lick our fingers to moisten objects (pages of a book, packagings)
- To touch food for other peoples (shops, collectivity, home...)
- In the toilets, to touch the flush handle, door handle, tap handle...
- To touch contaminated objects: money, items in a shop, door handles,
buttons of an elevator or money machine, pens, handrails, flush
handles, taps, and then using these unwashed hands to blow our nose,
to eat, touch our food, our mouth, our eyes...
The very actual risk of accident or taking over of the search in
genetics imposes to the governments to take immediatelly some commonsense
measures, without awaiting for an epidemics which could suppress
in first all the politicians and all the geneticians.
- To efficiently monitor the search in biology, to avoid any taking
- To systematically record all the genetic creations;
- From times to times, to pay some heed at advices of ecologists
and of ethics;
- To renonce to certain dangerous searches;
- In industry, to use modified bacteria only if SEVERAL cautions
are taken to prevent them to develop in the human body (for instance
to use only thermophilic bacteria)
- Systematic inquiry and search of any attempt to produce biological
weapons, past, present or future;
- Some secrecy may be useful to avoid certain dangerous methods
to spread; but EVERYTHING MUST BE SHOWN to control organisms in
charge of searching biological weapons.
...or at least to protect oneself individually 2003
But can we really trust governments who awaited twenty years before
reacting to detering issues such as the ozone depletion or the greenhouse
effect? Can we expect something of all this mass of grey and average
people, with whom we can never communicate, unable as they are of
only considering to change their behaviour? We begin to know the tune:
simply with denouncing a disgusting and useless habit, as to lick
ones fingers to turn the pages of a book, we shall only get back a
vaguely astonished look, or sniggers, we shall be called utopists,
pananoids, leftists, bourgeois, sectarian, anarchist, anti-freedom.
There are however only very simple things to understand, and, since
I was able to find them, everybody can find them too, and theoretically
I should not need to publish this page.
Happily, the hygiena methods described above are of an easy use for
all, without awaiting that the «majority» gets really
involved, nor than the governments organise it. Or course this methods
will give their full efficiency only if everybody use them. But, if
not, at least the people who are conscious and able to decide of
their behaviour can obtain some protection, or at least a selective
advantage over the unconscious, with the application of the following
Viruses are fragile; they do not survive more than several minutes
in the air, they cannot go throught skin, they fear soap. So it
is enought to oppose them a systematic barrier at every occasion to
get in the mouth, the nose, the eyes. It is quite easy; it is
enough to check all these occasions. But we need many attention, as
only one forgetting can make a hole in the barrier and be fatal. For
instance, many people wash their hands when they get out of the toilets.
But if, while turning off the water, they touch a tap that
everybody touched without never cleaning it, so this «hygiena»
is really illusory!
- The first thing hygienists remind us is to wash our hands
before eating (or touching our nose, our eyes). This is a good protection,
to the condition of not re-touching just after contaminated objects,
such as a tap, a door handle...
- So, in the toilets, and other specially contaminated places, to
touch objects only with a piece of paper cloth. Do not sit on the
seat, just stay a little above. To protect ourselves from splaches.
When we wash our hands, also wash the tap with much soap (before
- Alway carry some paper cloth with us, in town, in travel... and
never exchange the right side and the wrong side!
- But the most efficient method seems to be the muslim method:
to use the right hand for social contacts (other persons, objets...)
and the left hand for personnal contacts (to wipe in the toilets,
to blow and scrape our nose... and even to take our food). This
method breaks the contamination chain in most cases, without the
need for any other implement.
- Cough and sneeze in our sleeve, or in the hollow between the elbow
and the chest, toward the ground.
- Never cough and sneeze in the hand! It is the best method to contaminate
the most people!
- Do not spit.
- Abandon useless and disgusting habits such as to lick our fingers
to turn the pages of a book, seize a package, etc...
- Do not splutter. If we are not sure, avoid placing the person
we are speaking to in the trajectory.
- Facing peoples who cough, sneeze, splutter without care, to keep
away, to protect us. At need turn our back.
- The protective mask could become an indispensible implement to
get out in town, so long as people will maintain primitive habits
such as spluttering or coughing without care. Do not await for the
panic, buy some immediatelly (in pharmacy). Added in October 2020:
I had a box when the stay at home orders happened, for the covid-19.
Which allowed me to live normally (in the allowed limits) in an accute masks shortage! ha ha ha!
- If we can, avoid using the handrail.
- Objects such as keyboards, in cash dispensers, or locks, can me
manipulated with a key, or a least with the tip of the fingernail.
- Be careful with money: not content of already being dangerous
for the mind, it also gathers all the bacterias. Wash our hands
after shoping, or before eating.
- Avoid shopkeepers who touch money and food in the same time. If
we are a shopkeeper (baker...) to wash our hands, do not scrape
our nose, use paper cloths, use one hand for money and the other
- If some ask questions about our attitude, we can kindly explain
it ONCE. But if they do not change their own behaviour, it is generally
useless to insist.
- Al those who will mock at us or criticize our attitude necessarily
have a big problem. We shall be especially cautious with them, and
not try to reason them.
- Be careful with tramps and other who purposelly keep themselves
- Also be cautious with all the pig-headed, arrogant,narcissic
pervetrs, fascists, egocentered, etc... They will not care,
and will even contaminate others purposelly, as it is legal. In
epidemics times, these peoples will all turn in murderers.
- A stupid refusal to comply to simple hygiena rules could really,
in crisis time, place the governments in the situation to have to
take much more unpleasant and authoritarian measures...
- In a group, among friends, avoid to drink in the same glass, to
bite in the same sandwich, to use our hands to take food in the
same dish, to kiss everybody, etc...
- In a collectivity (boarding, dormitoty...) be specially cautious.
- In couple, or with our young children, we can be compelled to
pass over certain basic hygiena rules. So do it only at this occasion.
- All the sexually transmissible diseases could be eliminated in some years if
we stopped to practice sexual vagrancy (prostitution, collecting
partners...) Flee peoples with this kind of behaviours, and open
our intimacy only for a stable and time-lasting relation. For this
we must respect our partner, while not imposing him to bear our
character defilements. Let us refuse pornography, and come back
More general methods:
All these precautions may sound complicated and difficult to remember.
But there is a very simple mean to efficiently focus our mind on the
cautions to be taken. We have an instinct deeply rooted in us, and
easy to awake: the disgust of illness and of ill persons. During some
days, we think about all the occasions where viruses can pass into
us. This instinct will awake quickly, and it will soon warn us loudly
at each occasion! The only difficulty, in fact, is not to go too
far, not to indulge into paranoïa or in the contempt
of everybody. Keep our anger for the only who deliberatelly refuse
to apply these basic hygiena rules.
Especially to be put in quarantine may be very unpleasant; but we
must really understand that the governments have only this kind of
means at their disposal. They cannot avoid people to cough in their
hand and after have a handshake with us. So any person who will protest
against a quarantine will have to consider not to aim at the wrong
target: responsibles are egoïstic people, not governments.
Certain persons may wish not to be contaminated, but without bothering
to contaminate others. This attitude is false, as if, out of carelessness,
we create a danger for others, so we engage our karma, and even in
certain cases our responsibility in front of the law.
Certain people may think that to protect ourselves of certain contacts
with others may be to come back to a «bourgeois morals».
Such specious arguments already did much to hamper efficient steps
against AIDS. In facts, a minimum of hygiena absolutelly not prevent
to share some tenderness, love, ideas, enthusiasm, spirit, in brief
the most important, when sharing our mucus never brought anything
We can consider our effort of respecting other's health as a part
of our spiritual work, as our Karma Yoga.
We can also consider our effort of respecting other's health as a
part of our spiritual work to keep on a pure and poetical vibration.
Certain persons refuse the «religious beliefs». Me
I refuse the materialistic beliefs, such as for instance that the
evil we do to others would never come back to us. As a matter of facts,
nearby all the new diseases are linked in a way or another to the
nasty habit to kill animals to eat meat: -AIDS passed to humans
from poachers cutting up chimpanzees -SRAS and avian flu come from
animal farms -The mad cow would never had appeared without the mad idea
to make them eat meat. Curious as random can look like bad
At last an epidemics happening in the today conditions could lead
to a Darwinian selection of the people able to decide their own
behaviour, and to the elimination of all those who act out of
conditionning, ideology, social conformism, etc... (Written in 2003.
I shall not repeat in 2020...) As the catastrophe
which eliminated the dinosaurs, the modern epidemics could at last
profit to manking evolution. Some will shout after the injustice;
but in this incredibly happy epoch where more and more spiritual work
methods are available, everyone can gain his own freedom to place
himself where appropriate.
News of the front: avian flu, swine flu, 2009.
(Added in 2009)
It is interesting to see at least some official bodies like the
American Dietetic Association ending to advertise
the informations of this page.
Here, about cought, they seem to plagiarize me! But it is not that:
true ideas always end to be found independently by clever people.
However I allow myself to show some astonishment of the virtuous panic or our
public institutions, facing a swine flu epidemic which claimed
«only» some hundred lives, when previous epidemics claimed
thousands into the complete silence of the medias. But we better understand the
cause of this sudden compassion: this time pharmacy trusts claim to
have a vaccine ready in time... What better advertising than a
small quarantine, useless but well in sight of the medias!
Anover novelty is the scientific recognition of the role played by the
great concentration camps for animals doomed to butchery: SRAS, avian
flu, swine flu, everything comes from here. The specialists could even
track a camp in Mexico, where the swine flu appeared. Dreadful promiscuity,
deterent hygiena and exchange of reproductors made of these camps
true P4 genetic laboratories, in the open air, recombining and breeding
all kinds of viruses.
And this is not new, flu exists since tens of years...
And if we make laws for the «ethic treatment or animals»,
or for «organic meat», the camps will be simply globalized
into law less countries! The only solution to get out of thi hell is to
stop eating meat.
News of the front: Ebola 2014.
(Added in 2014)
Again, we hear about quarantine, checking of aircrafts... and of vaccines
which «will« come soon. This time the cause is deforestation,
which brings the populations in contact with fruit-eating bats, natural
bearers of the virus.
And of course, idiotic behaviours of «Ebola-deniers» hampering
the work of the teams on the field, while Africans residing in other
countries have to face totally unfounded accusations.
In short, we are still in the same point.
News of the front: Covid-19, 2020.
(Added May 05, 2020)
This pandemic of a highly contagious virus, of the calibre of the 1918
Spanish flu, with the potential to kill 100 million people, confirmed
the relevance of the warnings on this page. But it also shown that
some irresponsible politicians were not yet ready to take the necessary measures.
Korea has set an example, with systematic testing and searching for the
contaminated, eliminating the epidemic within a month, without containment.
Many countries waited for two or even three months, which found them unprepared,
and forced them in a containment policy, much more costly for both the economy
and for freedom.
France found itself a bit apart, totally unprepared, with its sadomasochistic austerity
policies which sabotaged our response capacities, or with president
Macron issuing an ultimatum to the virus, as to end up a strike. Added: It is only on
May 6, after four months of epidemics, that we read that tests, Korean way, were
systematically done, in a
mail from the ministry oh Health, Olivier Véran.
Finally, countries having elected populist governments practising denial,
incapable of discipline or leadership,
are paying the high price, with a record mortality rate. They risk becoming endemic
spots, and red zones with travel bans or quarantines on travellers
arriving from them.
On individual behaviours, I am proud to note
much more civism than I expected, fruit of the ongoing fast spiritual evolution of
mankind. Especially many groups and associations not intended for
this, turned into helpers. I am still seeing swines coughing without
protection, but this seems linked to minority
negative political opinions. Some people seem just unable to
accept any discipline, even in front of death.
Our allies the face masks, 2020.
(Added May 05, 2020, at the occasion of the Covid-19 epidemics)
One thing I did not foresaw was the relevance of face masks. They
however were of utter importance in 1918, and mandatory in many places.
Masks: The lie
The idea that the masks would be useless was first propagated by no less
than the WHO (Page deleted since).
Indeed, the global state of unpreparedness led to a shortage of
masks, and this pious lie allowed them to be reserved for those who
needed them the most: health workers. But by saying this, they were also
acknowledging the fact: masks are effective in protecting healthy people!
Since the WHO removed this lie, and it recommends the use of masks: «Wearing
a medical mask can limit the spread of certain respiratory viral
diseases, including COVID-19» (on their page on May 2,
2020). Recommendation with a warning attached: the mask is not enough, we
must also wash our hands, keep our distance, cough into our sleeve, etc.
all recommendations which are on this page for 17 years, with the hydroalcoholic bottle
which is in my car for 10 years.
The problem with such a lie is that it became a widespread belief, ineradicable
even by those who created it! And in France it is used as a pretext for doing
nothing about masks (and disinfectants too: in the country of wine,
at the fifth month of the epidemics, there is still no way to have alcohol!!).
At the moment I am writing (May 4), the only way to get masks is to order them on Amazon
at 0.4€ each, with a 2 months delay (In China!! No wonder this country is in the process of colonizing Europe)
This shortage of masks becomes an excellent pretext for black market, which
even not hides itself, with thefts and prices up to 5€! (reusable, dare we
hope). For those without memory, read «au bon beurre»
by Jean Dutourd, with the confirmation by a direct witness that this actually existed.
Added on May 22, 2020: if the risk of a black market is waning (at least in my
country, France), there is another one: that of «placebo masks»
for the general public, much less efficient than medical masks.
Added on May 22, 2020: Still no indication either on a recyclable
or biodegradable alternative to meltblown polypropylene, which will soon become
a big issue. Such an initiative would be an occasion to slow down the descent of
Western countries to the Third World, compared to Asian countries.
Added on May 22, 2020: For surgical masks (blue with three folds), the international
norm is ISO 1348514. In European Union, abiding to the european regulation
2017/74515 and the EN 1468316 norm allow for the CE marking.
For the FFP masks (rigid shell), the EN 149 norm defines three classes of firltration
efficiency: FFP1, FFP2 and FFP33.
Masks: the information
The problem is that there are a lot of different types of masks on the market, or people who
make their own, without really knowing the effectiveness of the different materials.
The wikipedia pages on surgical
masks and fabric
masks reflect this fuzzyness. What we however need are scientifically tested masks
with a stamp which guarantees their conformity.
We also need masks which are aesthetically pleasing, comfortable (remember these
pictures of Chinese nurses with sores on their faces), and above all
reusable, if we don't want an inflation of costs and wastes.
Here is a proposal for a simple signage, on the example of beach
mask: no danger, wearing masks is not necessary (but not forbidden:
this would require trust in the health authorities, discredited by the above lie).
☻ Orange mask: Wearing of masks is recommended,
but not enforced.
mask: Wearing of masks is compulsory, with coercive measures.
☻ White mask: special circumstances where we
must show our face, for example at an administrative desk, to prove our
identity. It would also be interesting to get back to the good old
hygiaphones... disappeared for some unknown reason.
Our enemies, meat and the sacking of nature, 2020.
(Added May 05, 2020, at the occasion of the covid-19 epidemics)
I started to warn in 2009 about the dire danger of
viruses recombinations and antibiotic resistance in concentration camps for
animals. By the time my voice was quite alone, but today it is a symphony
of calls by scientists, ecologists, social militants, artists, spiritual
people, to reduce or stop meat, and stop the terrible wounds we inflict to
nature every day. Each of our evil actions contributes, by a variety of ways,
to make us more sick, more unhappy, more lonely, more no future.
So it is clearly time to pass in the upper gear, stop meat, stop destroying
the last bits of nature, stop voting for crooks, clowns or morons.
Our enemies the conspirationnists, 2020.
(Added June 06, 2020, at the occasion of the covid-19 epidemics)
One thing I did not foresaw 17 years ago is that the conspiracy sickness would grow
to such an extent as becoming a major social handicap, and even a weapon
of political destruction. So, during the Covid19 epidemic, we
heard everything, accusations against this or that country for creating the
virus, opposition to health measures, opposition to remedies,
infatuation with false treatments, hazing and racism against
citizens of various countries, etc.
About the topic of this page, this situation poses a twofold problem:
☻What the conspirationists describe can
actually happen: pathogen created or released by accident or even intentionally.
Such accidents already happened before, as well as terrorist attacks,
and the Aum sect had anthrax labs! Fortunately, so far none of these
cases degenerated into an epidemic. But if this was
to happen, it remains possible that the information could be
censored, or muddled by contradictory «expertises».
☻If this was to happen (when it shall happen),
then there is a great risk that vital information would be received
as a conspiracy theory, leading to its rejection by society. This
would delay the necessary action or prevent finding the responsible.
For this reason, conspirationism must urgently be considered
as a serious social disease, just like racism.
Epidemics and Darwinian evolution, 2022.
(Added June 06, 2020, at the occasion of the covid-19 epidemics)
(Permalink) We can easily refute the conspiracy theories as what covid was created intentionally (as a solution to overpopulation, for the less worse theories). However, this should not blind us to the fact this is technically perfectly possible, and the motives of the perpetrators would not necessarily be so pretty.
Can a natural epidemic like covid, or an artificial one, exercise Darwinian selection on Humanity? Probably not for covid, because the number of deaths is far too low (0.075% of the population), and moreover, mostly old people who no longer pass on their genes. However, the warning at the beginning of this page in 2003 remains valid, and the foreseeable end of the covid epidemic does not diminish the probability of another epidemic, and even of a much worse one.
A disease can indeed produce a Darwinian adaptation. The history of epidemics even shows that this is frequent. However, these are mostly adaptations of immunity, which have little influence on the body or on the mind.
Where a massively lethal epidemic could produce an adaptation is by selecting people capable of good protective attitudes, while people who would be in denial, irresponsible or asocial, would be eliminated (a frequent case for covid). However, these characteristics are not hereditary, but only transmitted by education or by society.
So let us not wait for an epidemic much worse than covid to do our psycho-education, sitting quietly on our cushion.
