I'm reading a history of the 1918 influenza in the US and learned that early work on the effectiveness of masking was rejected by the physicians at the time as quickly as they could get away with it. It's been a century. Time to accept the science or get out of the way. My angry account of the past:

Russia’s Only Hope for Real Change Lies in Losing the War in Ukraine
Meaningful change in Russia is unlikely without defeat. Lessons from Germany show how accountability and reform follow war.

Public healthcare is not going to survive without public oversight.
There's no reason for it. Just that the public that benefits from it isn't allowed to see what goes on under the hood. We're prevented from looking out for our own interests by people who insist they're entitled to do it for us.

If Evidence Based Medicine has a poster child, it's the 2015 Antimicrobial Resistance and Infection Control study claiming N95s interfere with breathing in pregnant women.
Here's their setup, which they described as "simulating the actual wearing of an N95 respirator".
The RCT "gold standard" 🤣

Hey @ipaccanada.bsky.social if you're done unmasking the future, can we maybe let someone competent have a go this time?
If you're still practicing to botch H5N1, don't worry, you've got that. Canada has full confidence you'll screw it up by the numbers.
It's just...a break would be nice.

Hey @ipaccanada.bsky.social how about we try remasking the future?
This would be a good year to finally start learning from your mistakes, and I think we can all agree that your unmasking idea turned out to be spectacularly stupid.
So, what matters more to you?
Your egos? Or your job?
