As grievously bad as the ongoing pandemic of Covid-19 is now, the worst is yet to come. The complete lack of essential safety measures in public spaces means that current conditions will inevitably get much worse.

New Substack post about HEPA air purifiers. They're good, but not quite as good as the advertising might lead you to expect.

Do HEPA air purifiers really remove 99.95% of dangerous particles from the air?
The 99.95% claim is technically true, but misleading. HEPA air purifiers are good! But not that good.

Many of us with complex chronic illness learn a ton over years of neglect in healthcare settings.
We learn by painful trial and error and become confident about when to speak up.
But someone who’s never been sick? Someone who doesn’t speak the language or is critically ill?

This is how I make a seal cut at the nose on my kid's Zimi mask so that it fits better around her nose bridge, thus eliminating gaps around each side of her nose. The fit factor went way up on fit testing with this hack!

my colleague tells me

she is really feeling very sick,
and she is worried
she will need to leave early,
and though I want to note
that we’ve already been
in two meetings together,
instead I just say:
I’ll make my copies later.

I beg of you, please stop asking chronically ill people if we’re “better yet”.
We aren’t getting better. That’s the nature of chronic illness.
We may have good days & bad days… but we will always be sick. Its unrelenting. Always there. Ready to flare at any time.

Our 13-year-old crawled into our room 2 weeks after having a mild case of Covid & woke us in a panic because they felt like “their legs had been dipped in acid & set on fire.” It’s been 3 years & while the pain has decreased a bit, it’s still there every day + chronic fatigue and more. It’s brutal.
