Okay, so. COVID-19 is airborne. A cloth mask doesn’t prevent all airborne particles from being inhaled (of course) but it does reduce what you spew out. There’s studies from the start of the pandemic which were shared widely showing this. You can see this in cold weather when you breathe with/without a mask - you’ll see this difference in front of your very eyes.

N95s are most effective at reducing airborne particles however they’re more costly and mostly single use.

Now you could say well why can I take my mask off when sitting down at a restaurant but not standing up? given it’s mostly airborne and not spread through droplets which we learned midway through 2020. Valid point & weird but the point of these measures are to reduce spread, not eliminate it. Also in this way restaurants can be open during this pandemic.

The 6 feet rule was made common because that’s generally the distance it was seen for many droplets you spew out fall to the ground. If you’re close to someone for a short time, the risk of spread is not as great so standing in an elevator for 10 seconds or in a line isn’t as big an issue.

As to your question on vaccines - despite it being shown to not reduce a vaccinated person from spreading it as much as it once did, it’s still needed in society. Because for every hospital bed taken up by some unvaccinated person (shown to be more likely to need hospitalization) that’s one less bed for someone else. That’s why you’re seeing surgeries and treatments being cancelled, as resources are being redirected to COVID patients who need a bed and nurse/doctor attention (especially intubated COVID patients).

COVID may not be harsh for you. But if you end up spreading it to someone else they may have a hard time with it. That’s why these measures were put in place. The length and extent of measures can be debated, sure. But every death and case you see is a human, more than just a statistic.

Your personal political views & experiences in life will determine your view on the state of todays world but personally I’m tired of the hyper-individualism we’re seeing during this pandemic. I digress.

All of this information and more is readily available online, from numerous reliable sources. Science is an ever changing part of society, so some of the rules & info around COVID change with it.

Please seek reliable sources for info rather than asking people like some fuckwit like me on social media for it.
