Wasn't the 100 tampons thing because they didn't know how weightlessness would affect bleeding?
- That and NASA is a very safety conscious organization. So they want to overestimate everything and include way more than they need. So when she said a couple per day you can round that to 5 for safety, then considering it's a 6 day mission they want to include triple the amount of needed supplies which means 18 days worth. 18*5=90 which is pretty close to 100 so let's round up again. Plus tampons are a useful first aid tool, especially in zero gravity. You shove some into an open wound and it'll prevent blood from spilling all over the very sensitive equipment. Does a woman need 100 tampons for 6 days? Of course not, but she wasn't going to spend a week in the mountains, she was going to space, so the safety precautions were much more stringent
  
  It's also a weight thing. Tampons are pretty light, it's like one hundred per pound, so they probably said "we can budget x pounds for this" and didn't think much about the reasoning behind why they're sending several hundred tampons into space, but we're entirely focused on how.
  
  Just a word of advice, the tampon in a wound thing, as much as the Russian military might advise it, is not good medical technique. Do not use a tampon to plug a wound. It'll likely do more harm than good. Just apply pressure to it from the outside with your hand if you have literally no other option.
  
  I learned recently that in space you might not need to piss as the piss floats in your bladder.
  normally you get 3/4s full and really need a slash, but in space it can fill up totally without you feeling anything and then just bust out your urethra without notice.
  honestly, it was probably a fair point.
  
  NASA also does everything they can to save weight though.
  On later Apollo missions, they cut the number of band-aids in the lunar lander's first aid kit from 6 to 12 to save weight.
  
  Not that I disagree that NASA isn't safety conscious, but I've recently watched a video about the challenge disaster which seemingly could easily have been avoided if they had listened to the weather concerns or redesigned their solid boosters after issues were observed in the first place. I guess in that case they just got too complacent.
  
  My mom makes similar calculations for holiday dinners.
- NASA is obsessed with redundancy, especially when the weight allowance lets them run away with it.
  Add that to the fact that most of the engineers were men, and had literally no clue about how many tampons are needed for a normal woman on earth, and you end up with 100 being sent up for a two-week mission.
  
  LMAO TWO-WEEK also they could just fucking asked

Do people really use the term "hosting" when saying you're having someone over for the weekend? Because I'm getting sex worker vibes otherwise.
- Sure. In my mind, hosting is either for larger get-together that takes organizing and preparation or if someone is traveling to the area to stay with you for a few days.
  Hosting generally carries the weight of planning, organization and preparation that probably doesn’t go into just having someone over to hang out.
- Depends how grown-up we're trying to feel
- Been using that forever, even in the internet. Ever heard of LAN hosting?
  
  Is that the original cybering?
  
  That’s fucking the LAN port right?
  Do you pay it or does it pay you?
- I don't hear it often, but being a host to people in your house is a normal thing.

I feel like we're missing an important piece of the puzzle: are they an alcoholic?
- Anyone who drinks more than a few times a week in the US is likely an alcoholic. Put someone in the hospital and have them discuss their usage with nurses over a variety of days... you will get quotes like (1-2 per week and 1-2 per day out of the same person) then you will have a nurse ask what their weekend drinking looks like and they will say "around a six pack"
  Just my observations, maybe I work in a depressed part of the state.

100 NASA tampons
- Fuck it's actually real. Nasa engineers really suggested 100 tampons for 6 days
  https://www.poynter.org/tfcn/2021/did-nasa-send-a-woman-to-space-with-100-tampons/
  
  What would be the normal amount, just out of interest?
  
  Yup.
  Quick math and being paranoid about redundancy:
  A typical period lasts 3-5 days, with 7 being the high end. Round to 10.
  Heavy flow might require a change every 4 hours, or 6 a day. 12 a day is in the realm of reality, albeit medically concerning.
  Bring extra in case return has to be delayed for whatever reason.
  They're extremely light and small, so a conservative weight allowance holds a lot of them. About 1g each, or 100 per 4oz.
  So some quick math and padding your numbers to account for the unknown gets you 100, which considering they then asked isn't an unreasonable way to start.

Breweries already did the math for us - 1 case per dude.
- Per day
- How much is a case?
  Over here, beer is typically sold in crates of 20 bottles à 0.5l.
  
  Interesting. Where I live the standard case size is 24*0.3L.
  
  Here it's usually 24 cans of 0.33l. I haven't seen a crate of bottles in years

I tried too long to figure out what this has to do with the Lemmy app.

How could an adult actually be confused about this?
- idk, doesn't seem that crazy to me. if you don't drink or are a small person with a small tolerance, you might have no idea how many beers a person who drinks more might get through per night. don't want to underdo it and have them run out, don't want to overdo it and make them feel like you think they're a crazy alcoholic. and then obviously add a little d r a m a to it cause it's a tweet :)
  
  I mean if I wouldn't drink, I just wouldn't buy no alcohol at all. And if I would, I'd just buy twice the amount I drink if I don't know any better about the person.
- I don't drink, I'm always confused when hosting about the amount and type of beer I should buy. And then I'm stuck with beer afterwards the inevitably goes bad. Now I just let people BYOB because they typically did that regardless.
  
  You could make it a BMBH (Bring My Beer Home).
  
  I don’t drink
  Now I just let people BYOB
  Going to BYOB is the right call. Good on you for focusing on your strengths.
  
  I don't drink either and used to be in a club where I had to work a bar once a year. And every year without fail, I had to re-learn even just the basic categories of beer.
  (Where I live, there's like 7 different words to describe 4 different popular categories.)
- I grew up Mormon, and am only now figuring this all out. I have no idea about any of this
  
  It’s fairly well answered by basic information about alcohol serving sizes, DUI limits, and just the amount of fluids someone can take in over an evening. 1 can of beer = 1 basic dose of alcohol. 2 in an hour puts you over the legal limit for blood alcohol for driving. Someone could typically drink maybe a gallon of fluids in an evening regardless of what it is. Beer is sold in packs of 4-12, which are usually shared. So a normal amount of beer to get for someone who isn’t a regular alcoholic would be 2-6 for a night. It also varies with their weight and the strength of the beer (most is about 5% now but some is higher).
- Could also be a joke?
  
  Apparently we don't do jokes on Lemmy.
