Yes, potato chips are completely fine in that situation. I don’t know why people say they have too much salt. Sure, they have a lot, but when you have a cold, you’re supposed to drink a lot of water, so that balances out. You can lose a lot of salt due to sweating (especially if you have a fever) and peeing. And salt is a very important electrolyte. And the fat and starch gives you calories.
I think you would be fine for a long time if you drank old-style beer. Unfiltered, low alcohol content, some remaining sugar/starch and with lots of yeast, maybe some impurities that probably contain amino acids, vitamin b12 and other important stuff.
I believe I read that it helps with lung development when the fetus is swimming in the water in the womb or something like that. But otherwise not really useful.
The “q. s.” remains a mystery though.
q.s. means quantum satis and is Latin for “as much as necessary”. Which means they add enough for the right consistency or flavour or whatever, but the exact amount isn’t given and might vary.
Still sounds implausible and far fetched. Why would you be outside without adequate clothing? (Also below zero can be fine in jeans and sweatshirt if the sun is shining and there isn’t much wind). And in that case it would be more a heat issue and less like a shelter issue.
The other case also sounds more like a heat/water issue and less like a shelter issue.
Don’t like them either.
Security is there to make sure you’re not carrying illegal stuff, as long as that’s fine, the only time they maybe check the id is before giving you the boarding pass.
Looks like the guy didn’t have a boarding pass altogether, so not sure how he got into the plane.
There is usually a person or an automatic gate that checks your pass before allowing you through the plane. However that’s more like a ticket check and to make sure people don’t get on the wrong planes, it’s probably not super hard to get around.
