The Woes Of A Writer

I am going to SCREAM. My brain is currently 90% pigment particle size and 10% the optimal shelf placement for oversized stretcher bars. I swear, writing this artist mc fic is genuinely turning me into an accidental art supply expert, and half of what I'm learning I probably won't even use.

My mc works in an art shop, right? So he needs to know his materials. Which means I need to know his materials. And that knowledge is EXTENSIVE.

Do you know the exact difference between a kolinsky sable brush and a synthetic squirrel hair brush for watercolor washes? Because I do. Do you know the specific ASTM lightfastness rating for a particular tube of quinacridone magenta? I've researched it. I just spent an hour down a rabbit hole trying to understand the nuances of cold press versus hot press watercolor paper for different ink applications, including the cotton content and sizing methods.

And the colors. OH MY GOODNESS THE COLORS. "Would this particular shop stock a full range of Sennelier Artist Oils next to a more budget-friendly line of System3 Acrylics? And if so, how would the mc physically arrange them on the display rack to highlight quality while still making the cheaper options accessible?" "What's the best way to describe the texture of a freshly mixed, architectural-grade titanium white designed for exterior murals versus a standard tube of interior artist's white, in terms of viscosity and coverage?" "How does the shop's fluorescent versus LED lighting subtly alter the perceived hue of the 'mildly displeased pigeon grey' custom blend before it leaves the store, especially for a customer who's very particular?"

I am learning about the varying levels of archival quality for every single item – from the gesso on the canvases to the fixative sprays, down to the acid-free properties of backing boards for framed prints. I'm researching the ideal wood type for studio easels and the optimal way to prevent a stack of large format paper from warping due to changes in ambient humidity. My search history is a parade of "best palette knife shapes and their steel composition," "drying times of various oil mediums (linseed vs. walnut)," and "proper storage of pastel sticks to prevent smudging and breakage."

And here's the kicker: half of this incredibly granular detail, this deep dive into the very fabric of the art world, might just end up as a single, passing sentence or a subtle background detail that only I will appreciate. Regulus might just pick up a brush, not a number six synthetic round filament brush with a seamless nickel-plated ferrule designed for fine detail work. But I know the difference. I know it all.

Send help. Send coffee. Send a memo telling my brain to chill out on the unnecessary but fascinating facts. I'm in a research spiral.voi

[i-still-mask-because]

in the wake of all this new information during COVID, do you feel that maybe we should all just be masking all the time, COVID of no COVID? I mean it can't be the only airborne disease out there and immunocompromised ppl have always and will always exist so like. Following that thinking even if we don't have COVID we could still be risking other people's health (and lives) with other diseases we may have right? Idk I'm stressing a lot about this do I just need to wear a mask outside forever cos. Masks mess with my breathing and sensory issues and stuff but. I don't wanna?? Kill people by accident??? Aaaaa

Hello, thanks for reaching out about this.

I saw this ask about a month ago, and I needed time to think about how I'd respond to it (so I want to thank you for the patience!).

I'll try to answer all of this to the best of my ability, and I thought I'd answer this by going backwards (responding to the last things you said and then moving up with responding to the first things you said).

Everything is below the cut because this is very long!

First I'll try to summarize what I think you're asking here:

"Vulnerable people exist in this world all around me, therefore does this mean I'm constantly posing a threat to those vulnerable people's safety when I don't mask? The thought of this brings me feelings of stress, fear, and anxiety."

I find this is hard to answer candidly without risking stressing out you or anyone else who's aware of the consequences of their choice not to mask. Nonetheless, my honest answer is: yes, choosing not to mask means risking the lives and safety of vulnerable people, i.e. the disabled, immunocompromised, elderly, children & babies, and those that intersect those groups. That risk can take place directly (such as interacting with an immunocompromised elder) or indirectly (such as interacting with the parent of a disabled child).

I also want to add that it's not only those groups that need protecting. I firmly believe that regardless of your age and/or whether or not you self-identify as disabled or immunocompromised that everyone is at risk of the long-term consequences of this rapidly mutating, vascular, and immunosuppressive virus. No one is invincible to this, and I'll add: not even if you're vaccinated (still get vaccinated if you can, but know that you can still catch covid & develop long covid regardless of your vaccination status).

1. "Masks mess with my breathing and sensory issues."

I understand how that can be difficult to deal with, trust me. There are specific masks (such as most standard KN95s) that irritate the hell out of my face after a certain point. The way those specific masks brush against the hairs of my cheeks just make me want to rip the mask off my face completely. Finding alternatives has been a lifesaver, and they've allowed me to get through the day without wanting to maul someone lol. I don't know what masks you have tried out already, so I'll just recommend the one's I like as well as the one's I've heard good reviews on from people that also have sensory issues:

NIOSH 3m Aura N95 Respirators

Flo Mask

GATA Mask (Haven't tried this one yet, but I've heard a LOT of people say this has been a game changer for them because of how comfortable it is & how it doesn't trigger much sensory issues at all due to its silicone material. Probably the only con I've heard is the chance of the build up of moisture in the mask after a long period of use & water possibly dripping on your face— this happens to me sometimes with my Flo Mask. Edit on Sept. 26, 2023: I tried GATA Mask, and I personally have a tough time getting a comfortable fit & seal with it, even when getting the small/medium size for adults to see if it'll make a difference, and the nose bridge shape not fitting well for me is a huge con. Customer service is just suggesting I spend more, so I'll just give this one a break, for now at least. A lot of other people seem to like it though.)

Halyard FLUIDSHIELD [ASTM Level 3] Mask (My mom works in a hospital, and these are masks she brings home from work. They're VERY comfortable for me, especially when I'm masking at home. I recommend finding a way to tighten the loops that go around your ears to prevent as much gaps around the mask as possible. If tight loops hurt your ears easily, I recommend a mask brace.)

O2 Nose Filters (I haven't tried these out yet as well, but I've seen videos demonstrating how effective these are at filtering out SOOO many unseen particles. I don't recommend using these alone of course, because there's still a risk of inhaling harmful aerosols through your mouth. I would recommend using this as a reinforcement of the protective measures you take. For example: adding on a comfortable surgical mask— ideally one with a high filtration efficiency like the previous suggestion— with the nose filters. I think these nose filters would be great if you're removing your mask real quick to take a sip of water or if you're outdoors with enough distance from crowded areas & groups.)

In the ideal world, more people would mask during this on-going pandemic so those that deal with sensory issues and/or those that straight-up can't wear a mask due to medical reasons wouldn't have to worry so much about choosing between existing & risking their health. For now, we just have to find alternatives.

2. "Do I need to wear a mask outside forever?"

My answer to this is: yes until further notice. There's no foreseeable end to this pandemic right now, but it would be worth the patience to wait for adequate tech, treatment, and cures for covid-19 to be released before even thinking about getting loose with masking.

Societal mandates have been dropped way too soon, and public health in regards to covid-19 is being forced on us as an individual responsibility. As a consequence, this gives this rapidly mutating virus a lot of wiggle room to spread and do whatever it wants. This means doctors and experts don't have much answers yet for adequate treatment because there's a MAJOR lack of containment (such as masking & quarantining) and documentation (such as testing & reporting). This isn't to say there hasn't been any advancements whatsoever: for example, Washington University just developed a breath test for covid that gives results in just 1 minute! This is great news! And this is just one reason why it's very necessary for those who can mask to mask, so scientists are given more time to roll out helpful solutions & tools sooner.

Another thing I'll add is if you're symptomatic and/or are positive for covid, you should 100% be wearing a mask no matter what, point blank period. I say "and/or" because it is VERY much possible to have covid and not experience any symptoms at all; this is a major reason why it's necessary to mask up in public consistently, because you can't always know who you bump into that may have covid or not.

3. "Even if we don't have covid, we could still be risking other people's health (and lives) with other diseases we may have right?"

Yes, there is a possibility of spreading airborne diseases to vulnerable people unknowingly— without the protective & preventative tools that is.

I can only speak for America because that's the cultural zeitgeist I grew up in, but: I feel like many of us can agree that, unless you worked in a healthcare setting, what was "normal" (in America) before 2020 when it came to airborne illness prevention was definitely not the regular use of a mask. American health education mainly taught us if we're coughing & sneezing to try to do so in a tissue or into your elbow, as well as frequently wash our hands. That doesn't account for the way air actually works though. For instance, if someone with the common cold coughed into the inside of their elbow, the particles they coughed out are still able to linger in the air because their elbow isn't creating a tight seal around their mouth (their elbow may have caught the droplets from their cough— which are bigger & heavier— but the smaller, lighter aerosols would just spread around similar to how smoke does); it's the difference between 😪 vs 😶‍🌫️. The only sure way for the germs they've coughed out to be blocked from spreading to other people is if they wear a well-fitted, quality mask/respirator.

I feel like health education from a young age should include the benefits of masking; that way it would be easier to adapt to the need to put on a mask to protect ourselves & others as a collective. It would be phenomenal & wonderful if we as a collective were used to masking the same way we're used to putting on socks before putting on our shoes.

4. "Immunocompromised people have always and will always exist"

Yes, that is true. And that means necessary measures taken to protect them, as well as other vulnerable people, should be the standard.

5. "[Covid] can't be the only airborne disease out there"

Of course not. There's plenty of them. However, not all airborne diseases are the same, nor should they be treated as such. What's been observed in regards to the long-term effects of covid is not at all the same with other airborne diseases. Covid is a highly contagious virus that is more than just a respiratory disease. Its goal is to attack your immune system, nervous system, heart, brain, and/or other vital organs. That's what viruses do. They act smart and sneaky, and they have the capability to trigger illnesses in your body that you may not have had pre-infection:

Chickenpox is known to lead to shingles

Epstein-Barr is known to lead to mono

HPV is known to lead to cancer

Covid-19 has been found to lead to:

POTS

ME/CFS

Stroke & Heart attack

Alzheimer's

Dementia

"Brain Fog"; Memory & Concentration Problems

The list goes on, and these are only what we know of. Covid may not be the only airborne disease, but it definitely is a dangerous one with serious, long-term negative effects.

6. "Do you feel that we should all be masking all the time, whether or not covid-19 exists?"

In regards to masking with the existence of covid:

Yes. Masking is a vital method in the prevention of catching & spreading covid-19, because it is primarily spread through the air.

In regards to masking without the existence of covid:

See my answer for number 3, and also: given the fact wearing a mask can only do more good than harm for most folks, I don't see why not. Imagine a world where we don't have to worry about flu season or allergy season anymore because those aerosols are filtered out from consistent mask wearing. Sounds like the dream to me lol.
