So...1 in 24 Canadians has Covid, XBB1.5 (kraken) variant is projected to be at 22% in Ontario by the end of the week, people are still dying of Covid (279 in Canada in the first week of January), and though voluntary mask wearing is low, 69% of Canadians support mask mandates if necessary.

Public health in many regions recommends or strongly recommends mask wearing.

But no mask mandates?
Not even in education and the workplace?
Nothing?

Mandates would make it so much easier for the caring majority to normalize wearing a mask again. Many people understandably don't want to unless it is clearly necessary. are necessary to get mask wearing in public up to >80%, which IHME estimates would halve deaths from covid with a month.

In the absence of clear direction from public health, and protect yourself and those around you as best you can.

#Introduction (I guess).

Old.

40 years in #IT, from #soldering #components onto #breadboards to #managing #multi-national #systems. Was fun, then it got boring.

20 years (started late) as a #volunteer #firefighter, from newbie to Group Officer and #educator of #firefighters and the public. Loved it!

15 years of working #sound and #lights for the #stage, from #musicals to #groups. Loved that, too.

#Pyrrhonist - I’m an #unbeliever. In anything. I only trust #sources that have #evidence.

It doesn’t need to be said, but I’m consistently impressed by the level of discourse here on #Mastodon. Thank you all for being thoughtful, kind, and engaged in your posts and your replies. I’m learning so much from all of you. The #Fediverse rules ❤️

#introduction "Late to the party" seems to be my default motto. Just learned of Mastodon today. I'm a retired guy who moved (from Monterey CA) to (Victoria BC) Canada in 2017, and I find I like it here.

Current interests: cooking (including fermenting vegetables and making — I like to make my own mix), blogging (leisureguy.wordpress.com), shaving (seriously — done right, a great way to start the day), old jazz, watching movies, observing, and learning. Strong proponent of the Oxford comma.

Hi👋🏾. It's my birthday today & I just want to say that:

✔️ Housing is healthcare
✔️ Public healthcare is worth saving
✔️ There is no justice without disability justice
✔️ Racism is still a public health crisis
✔️ Compassion is contagious

Thank you all for the birthday love. ❤️

@holmesr@mastodon.online @Pat I didn't know that. In the early pandemic most frontline workers with access to N95s and no religious objections, were clean shaven for this reason.

@holmesr@mastodon.online @Pat

yes, that's correct. But at any level of stubble, the N95 is best.

You can't pass a fit test with stubble.

Should have been more specific: Aura 1870+ is the one with stretchable elastic

Hi again. Thanks for the feedback and for engaging, much appreciated.

We think overhead elastic is critical to getting good fitted-filtration (ie, net filtration of a mask on a face). We summarize this here ⬇️

maskevidence.org/head-attachme

In North America, must have overhead elastic simplifying our advice in favour of these over or

There are data on beards, too!

For a 10mm beard, an N95 is still more effective than all other masks.

If the stifling feeling is specifically associated with headstraps for you, they could be too tight. Aura 3M has simple band elastic straps that lengthen with a good hard tug. This is a pro in this situation for you.

For straps that don't lengthen so easily, consider an with braided elastic such as Vitacore's .

Vitacore's Can99 also has superb breathability so if the problem isn't the attachments, this might help.

Apologies for a N American reply to a European question.

Anyone curating info on or and suppliers please let me know: we would love to put this on our website.

Hi! It sounds like you are still using the distinction at 5 microns between droplets and aerosols. This has been recognized as incorrect. Your 'droplet' that doesn't settle is more correctly described as an aerosol

Such a cool idea! @natematias & team developed software to run n-of-1 trials in personal tech use. Just like a randomized trial, but you are your own control.

They ran one on whether changing your phone to grayscale reduces phone addiction. You'd get a message on what to set your phone for the day & feed data in: you got your results back, & they analyzed everyone's.

The result of this proof of concept? 14 people did it. (Overall, switching off color didn't reduce time on phones.) ...1/2

Her shameless remarks to a child victim of the Holocaust caught on video, the UK Home Secretary then used her office to pressure an independent organization to remove it. They did not. Also: fuck her.

I obviously need to pin a post about this again which is forcing me to create a new one.

Nobody on social media owes anyone else an explanation for how and what they post. Nobody needs to roll up and tell people what and how to post.

Nobody owes anyone else an explanation for how they present themselves online, most especially anyone in a marginalized or threatened group. Nobody should have to share or be forced to share any more information about themselves than they want.

People usually come to a social media platform to meet like-minded people and relieve stress, not make new stress. Give people a break.

We have moderation rules. They’re reasonable. We stick to them.

And if you don’t like it, just don’t follow me or anyone on this instance. We don’t care. We’re fine. You don’t need to tell us.

We’re way past explaining it. We’re just going to block you.

The anion gap was not always a thing and we have nephrology legends Robert Narins and Michael Emmett to thank for popularizing it in this amazingly comprehensive manuscript.

These are called electrets. Tiny dipoles with positive and negative ends.

N95s only, not medical/surgical

Evidence on silk didn't pass muster and that's why we don't include it.

Here's an evidence based summary on materials for cloth masks⬇️
