One of the rarely sung heroes that got us to the moon, Mary Sherman Morgan. Responsible for the fuel that got us there.

en.wikipedia.org/wiki/Mary_Sher…
Who, one might ask! You see, Werner von Braun and his, by Jupiter C days, considerable gang of engineers and scientists, well funded and much acclaimed were unable to come up with a fuel formulation that would eventually get us to the Moon.
Stumped and feeling the heat, the former Third Reich rocket engineer, began to scour the defense-contractor establishment for anyone that could solve the problem...which, as most of us know, displayed itself in exploding rockets just above launch pads, time after time.
At last, they came upon the basically invisible Mary Sherman Morgan, who, working as a defense contractor chemist, a woman of distinguished, but hidden talent and accomplishment throughout WWII and in the post-war world, was prepared to bail them out.
She came to assemble the team that developed "hydyne." This fuel was the salvation of the space program. This was the jump start that led to Saturn V!
Who was she?

1) fugitive from an abusive home.
2) a minimally educated chemist
3) a mother
4) a genius
5) likely autistic
Her career and accomplishments were discovered in a box, destined to be thrown out, trashed from the attic of the home where she died. Discovered by her son, who, along with everyone in her family, was completely unaware of this remarkable person's accomplishments...
...and contributions to all of mankind. He wrote a book, Rocket Girl" about his remarkable Mother. It seems that one of those first giant leaps for mankind was made by yet another incredible woman, Mary Sherman Morgan.
Look at the Moon tonight, dream about Mars and what will be, and in addition to all those we know, add Mary, who escaped from the prairies of the Midwest, who extended our reach for the stars.

"More people die of the flu every year, you're just fear mongering"

No, more than 140k Americans do NOT die from flu a year. No matter how you calculate them.

2017-18 was the worst recent year and the CALCULATED deaths are still only around 61k tops.
(61k is less than 140k in case you were wondering).

And those are the CALCULATED deaths for a YEAR. That's the number that we come to using the numbers of confirmed deaths, the number of total deaths, and a bunch of math after the season is over.
We figure out how many of those total deaths were almost definitely actually flu. For comparison, the CONFIRMED deaths for flu in an average year is 2-3k. Yes, 2-3 thousand. Again, far less than the 143,000 confirmed COVID-19 deaths in the U.S. in six months.

So yesterday I talked about testicles and COVID-19. Opinions on ovaries are a little more mixed but...

TLDR: Ovaries probably have enough of the same receptors that if testicles are affected, so can ovaries be. So, if you have any interest in protecting your organs, wear a mask
ACE2 is expressed pretty widely through uterus/ovaries/placenta. ACE2 is the primary access point for the SARS-CoV-2 virus

pubmed.ncbi.nlm.nih.gov/32365180/
ACE2 isn't largely co-expressed with TMPRSS2 in reproductive tissues, which should make them less vulnerable. But this holds true for testicles too, and that doesn't protect them. No reason to think it would protect ovaries or uteri.

Need another reason to wear a mask, socially distance, and stay safe?

SARS-CoV-2 gets into cells mostly via the ACE2 receptor. Know what tissue has a lot of ACE2 receptor (besides lungs, gut, heart, etc)?

TESTICLES.
Especially a worry for those young people who "aren't affected as badly" by COVID-19, because you might not be breathing hard, but your dangly bits might be getting permanently toasted.

Don't want your spermatogenesis and steroidogenesis screwed with? Stay home and mask up.
"The main host receptor of the SARS-CoV-2 is angiotensin converting enzyme 2 (ACE2), a major component of the renin-angiotensin-aldosterone system (RAAS). The ACE2 is also involved in testicular male regulation of steroidogenesis and spermatogenesis." ncbi.nlm.nih.gov/pmc/articles/P…

The "readability survey" on @ravelry is inaccessible as hell, and fails to address many of the primary concerns with the layout.

It's also incredibly ineffectively written if you actually want usable, useful data out. @outcassed and @ravelry , hire an accessibility consultant!
Seriously, 35 pages and nothing on the flickering drop shadows besides a ticky box asking if you use the setting?
"Which do you prefer?"

I prefer not having to lie down after 5 minutes of using @ravelry, or after spending 5 minutes flicking between survey options.

So let's say you have pneumonia. It's not looking so hot.

Then you get terminal cancer. You've got a week to live.

Suddenly someone comes in and stabs you in the chest with a knife.

What do you want marked as the cause of death?

That's right: Bleeding from knife wound
Lucky for you, this is how it works! (mostly)

If you're dyING of something, but something else comes in, takes advantage of that, and kills you (you can't fight back against knife guy because of cancer and pneumonia) it's still the knife that killed you.
My dad has heart disease and diabetes. If someone breaks into his house and kneels on his chest until he dies...

The cause of death is lack of air caused by chest compression, even if his conditions make that easier.
