So Voyager found out there is this bubble surrounding our solar system made up of solar material blown outwards by solar wind and acts as a border between the solar system and the rest of space has a temperature of 30,000-50,000 Kelvin.

For reference the surface of the sun has a temperature of roughly 5770 kelvin

The way to fix a disturbing number of problems is "Cultivate good habits, and then do them consistently." I do not like this. 😠

You can survive almost anything through the right combination of:

Bitching and moaning

Hater-ology

Doing a goofy little bit about it

Having a buddy say "that's so fucked up" at intermittent points (you can also be your own buddy)

Destroying the cursed amulet you carry everywhere, why do you even have that thing

I think everyone severely underestimates how much iron women need compared to men. Lets put things in context first: beef contains about 1-3mg of iron per 100g/3.5oz, depending on the cut.

men and women are somewhat similar in iron demands up until 14 and then a huge change at 19 onwards. 19 year old+ men need around 8mg of iron a day. so like. a single large, or two small steaks. of course you get iron from things other than beef, and they'll likely get enough on any normal daily diet.

women need 18mg of iron a day and TWENTY SEVEN when pregnant. that's over TWICE the male requirement for your entire life and over three times when pregnant. THATS A LOT?? look at ur own diet for a minute and i promise you, unless ur going crazy on oats and chickpeas or something, you are NOT getting enough iron. probably not even close.

and I'm mind-blown by this because somehow, culturally, meat/red meat seems to be a more stereotypically masculine thing. when eating out, women get a salad and men get a burger or a steak. you google "person eating steak" and vast majority of results are men - when there are women, they've also got a cute little salad on the side, meanwhile men tend to have plates full of meat. (seriously. go google this. it's crazy)

WOMEN: YOU NEED TO EAT TWICE AS MUCH IRON-DENSE FOODS THAN UR BROTHER, UR DAD, UR HUSBAND ETC. MORE THAN TWICE AS MUCH. NO WONDER YOU FEEL FUCKING TIRED AND WEAK ALL THE TIME.

By the way, for anyone wondering, chicken hearts contain about 9mg/100g and don't taste that bad. it just tastes like chicken. i know this sounds so gross but i pan fry around 500g, pop it in the fridge and eat them cold throughout the day, split it across 3-4 days (don't eat past 3 days refrigeration). i promise its not that bad. (they're SO cheap btw. by far cheapest meat on the market, let alone meat with high iron. i get those 500g batches for THREE DOLLARS meanwhile a 200g steak is $15+ and doesn't even cover the iron i need). chicken liver is also really good and cheap but i cant vouch for the taste.

Flatworm Dugesiidae sp

Collected from the stem of an emersed iris. The pigmented spots camouflage it with the river mud, and the eyespots help it find dark niches.

we need to have a way to post a pdf directly to tumblr. tumblr should have another post type called "pdf" so we can embed them easily. tumblr will never be the new pdf without this function.
