😷 دو تا ماسک روی هم بزنیم بهتر است یا یک ماسک خوب بزنیم؟ یک ماسک خوب (مثلاً N95) از چند ماسک روی هم زدن بهتر است، چون اغلب اشخاص که دو یا سه ماسک زدهاند ماسک، روی صورتشان فیت نشده در نتیجه اثر کافی ندارد. (هوا از اطرافش عبور میکند.)
از فروشگاههای معتبر (نه دستفروشها) ماسک خوب بخواهید.
ماسک باید طوری روی صورت قرار بگیرد که هوا اصلاً از اطرافش عبور نکند.

Friday’s performance was part of a larger shift. For the week, the Dow, S&P 500 and Nasdaq fell 2%, 2.9%, and 3.5%, respectively. If you initiate a Secret Chat, however, then these communications are end-to-end encrypted and are tied to the device you are using. That means it’s less convenient to access them across multiple platforms, but you are at far less risk of snooping. Back in the day, Secret Chats received some praise from the EFF, but the fact that its standard system isn’t as secure earned it some criticism. If you’re looking for something that is considered more reliable by privacy advocates, then Signal is the EFF’s preferred platform, although that too is not without some caveats. The gold standard of encryption, known as end-to-end encryption, where only the sender and person who receives the message are able to see it, is available on Telegram only when the Secret Chat function is enabled. Voice and video calls are also completely encrypted. That hurt tech stocks. For the past few weeks, the 10-year yield has traded between 1.72% and 2%, as traders moved into the bond for safety when Russia headlines were ugly—and out of it when headlines improved. Now, the yield is touching its pandemic-era high. If the yield breaks above that level, that could signal that it’s on a sustainable path higher. Higher long-dated bond yields make future profits less valuable—and many tech companies are valued on the basis of profits forecast for many years in the future. Asked about its stance on disinformation, Telegram spokesperson Remi Vaughn told AFP: "As noted by our CEO, the sheer volume of information being shared on channels makes it extremely difficult to verify, so it's important that users double-check what they read."
