A short thread on how face masks work, why we wear masks *to protect other people from ourselves* and not the other way around, & why wearing face-shields without a mask, masks with valves, or masks that hang open on the bottom or sides IS ACTUALLY DANGEROUS FOR EVERYONE ELSE...

I am going to start off by citing from a great paper by @trishgreenhalgh about the benefits of mask wearing, which you can read in full here: https://t.co/l0NfuU85cZ
Masks can work in 2 ways: protecting the wearer, & protecting other people from exhalations emitted by the wearer. Surgical grade masks are supposed to do both. They block out small particles emitted by the source, AND they filter those particles out from other emissions
For cloth masks, however, they are not so good at filtering out tiny particles which can contain viruses. But what they are good at doing is limiting the large droplets people give off when they breathe or cough – before they become aerosolised.
This means when you wear a cloth mask, the most important role that it plays is not protecting you from other people's exhalations but *protecting them from yours*. @trishgreenhalgh calls this 'source control' i.e. 'protects other people from droplets emitted by the wearer'
Unfortunately most people seem to think they are wearing a mask to protect *themselves* from everyone else. Which, unless you are wearing a fancy medical mask with a fancy rating, is not only selfish but also incorrect.
What cloth masks are supposed to do is filter the air you breath out, right at the source. This blocks large droplets as they are emitted, before they can become smaller aerosols (which are harder to block & can more easily make their way through another person's cloth mask)
Early on, when people were (mentally) struggling to breath with a mask on, lots of people bought & sold masks with vents. This meant what the wearer breathed in was filtered, but what they breathed out (via the vent) was not. So, no source control.
The same goes for these terrible 'half face shields' now on sale, that cover the nose & lower part of the face with clear plastic but are *open at the bottom*. This actually means both inhalations AND exhalations are not filtered by anything. You might as well not wear anything.
the same applies if you have a mask – even a medical grade one – that does not fit or is not properly tied, and has gaping holes under the chin, above the cheeks, or on the side of the face. If there are gaps where air can get in or out, your mask is pointless and even dangerous.
Masks made using only one layer of fabric – like buffs – are also not great at doing anything except making it look like you are wearing a face cover. Which is why most medical centres etc won't accept them. They are ok-ish for exercising outdoors, and can be worn by kids.
Face shields by the way have similar flaws *as masks* (which they are not, which is why they *must be worn together with a mask* and are not sufficient on their own). Shields are barriers not filters, and may protect the eyes, eg.
Bottom line:
The reason you wear a mask because *you* could be a source of SARS-CoV-2.
If you wear masks that allow your breath to leave unfiltered by layers of cloth, you may as well not even wear one.
Please, for all of our health, wear a proper mask and wear it properly
Also, thank you to @trishgreenhalgh who has been sharing and publishing this knowledge for nearly a year, and for all the other medical professionals who have been doing everything they can to teach us about *why* and *how* masks work to protect other people.

More from Society

So, as the #MegaMillions jackpot reaches a record $1.6B and #Powerball reaches $620M, here's my advice about how to spend the money in a way that will truly set you, your children and their kids up for life.

Ready?

Create a private foundation and give it all away. 1/

Let's stipulate first that lottery winners often have a hard time. Being publicly identified makes you a target for "friends" and "family" who want your money, as well as for non-family grifters and con men. 2/

The stress can be damaging, even deadly, and Uncle Sam takes his huge cut. Plus, having a big pool of disposable income can be irresistible to people not accustomed to managing wealth.

Meanwhile, the private foundation is as close as we come to Downton Abbey and the landed aristocracy in this country. It's a largely untaxed pot of money that grows significantly over time, and those who control them tend to entrench their own privileges and those of their kin. 4

Here's how it works for a big lotto winner:

1. Win the prize.
2. Announce that you are donating it to the YOUR NAME HERE Family Foundation.
3. Receive massive plaudits in the press. You will be a folk hero for this decision.
4. Appoint only trusted friends/family to board. 5/
Imagine if Christians actually had to live according to their Bibles.


Imagine if Christians actually sacrificed themselves for the good of those they considered their enemies, with no thought of any recompense or reward, but only to honor the essential humanity of all people.

Imagine if Christians sold all their possessions and gave it to the poor.

Imagine if they relentlessly stood up for the widow, the orphan, and the foreigner.

Imagine if they worshipped a God whose response to political power was to reject it.

Or cancelled all debt owed them?

Imagine if the primary orientation of Christians was what others needed, not what they deserved.

Imagine Christians with no interest in protecting what they had.

Imagine Christians who made room for other beliefs, and honored the truths they found there.

Imagine Christians who saved their forgiveness and mercy for others, rather than saving it for themselves.

Whose empathy went first to the abused, not the abuser.

Who didn't see tax as theft; who didn't need to control distribution of public good to the deserving.

🌺कैसे बने गरुड़ भगवान विष्णु के वाहन और क्यों दो भागों में फटी होती है नागों की जिह्वा🌺

महर्षि कश्यप की तेरह पत्नियां थीं।लेकिन विनता व कद्रु नामक अपनी दो पत्नियों से उन्हे विशेष लगाव था।एक दिन महर्षि आनन्दभाव में बैठे थे कि तभी वे दोनों उनके समीप आकर उनके पैर दबाने लगी।


प्रसन्न होकर महर्षि कश्यप बोले,"मुझे तुम दोनों से विशेष लगाव है, इसलिए यदि तुम्हारी कोई विशेष इच्छा हो तो मुझे बताओ। मैं उसे अवश्य पूरा करूंगा ।"

कद्रू बोली,"स्वामी! मेरी इच्छा है कि मैं हज़ार पुत्रों की मां बनूंगी।"
विनता बोली,"स्वामी! मुझे केवल एक पुत्र की मां बनना है जो इतना बलवान हो की कद्रू के हज़ार पुत्रों पर भारी पड़े।"
महर्षि बोले,"शीघ्र ही मैं यज्ञ करूंगा और यज्ञ के उपरांत तुम दोनो की इच्छाएं अवश्य पूर्ण होंगी"।


महर्षि ने यज्ञ किया,विनता व कद्रू को आशीर्वाद देकर तपस्या करने चले गए। कुछ काल पश्चात कद्रू ने हज़ार अंडों से काले सर्पों को जन्म दिया व विनता ने एक अंडे से तेजस्वी बालक को जन्म दिया जिसका नाम गरूड़ रखा।जैसे जैसे समय बीता गरुड़ बलवान होता गया और कद्रू के पुत्रों पर भारी पड़ने लगा


परिणामस्वरूप दिन प्रतिदिन कद्रू व विनता के सम्बंधों में कटुता बढ़ती गयी।एकदिन जब दोनो भ्रमण कर रहीं थी तब कद्रू ने दूर खड़े सफेद घोड़े को देख कर कहा,"बता सकती हो विनता!दूर खड़ा वो घोड़ा किस रंग का है?"
विनता बोली,"सफेद रंग का"।
तो कद्रू बोली,"शर्त लगाती हो? इसकी पूँछ तो काली है"।
Хајде да направимо мали осврт на случај Мика Алексић .

Алексић је жртва енглеске освете преко Оливере Иванчић .
Мика је одбио да снима филм о блаћењу Срба и мењању историје Срба , иза целокупног пројекта стоји дипломатски кор Британаца у Београду и Оливера Иванчић


Оливера Илинчић је иначе мајка једне од његових ученица .
Која је претила да ће се осветити .

Мика се налази у притвору због наводних оптужби глумице Милене Радуловић да ју је наводно силовао човек од 70 година , са три бајпаса и извађеном простатом пре пет година

Иста персона је и обезбедила финансије за филм преко Беча а филм је требао да се бави животом Десанке Максимовић .
А сетите се и ко је иницирао да се Десанка Максимовић избаци из уџбеника и школства у Србији .

И тако уместо романсиране верзије Десанке Максимовић утицај Британаца

У Србији стави на пиједестал и да се Британци у Србији позитивно афирмишу како би се на тај начин усмерила будућност али и мењао ток историје .
Зато Мика са гнушањем и поносно одбија да снима такав филм тада и почиње хајка и претње која потиче из британских дипломатских кругова

Најгоре од свега што је то Мика Алексић изговорио у присуству високих дипломатских представника , а одговор је био да се све неће на томе завршити и да ће га то скупо коштати .
Нашта им је Мика рекао да је он свој живот проживео и да могу да му раде шта хоће и силно их извређао
