I am just speculating, but in many diseases like rabies and chickenpox you can give the vaccine after exposure to help the immune system fight the infection. It's because the period between exposure and symptoms is quite long, often more than a month for rabies for example.
HIV can stay in the body for years before developing AIDS. So you can actually recruit people that have been tested positive recently and have not developed the disease.
I don't know but these fossils are often very fragile and can even collapse under their own weight when unearthed. There is little chance something like this would have survived centuries.
> They likely were, and think of me what you like but I've noticed the same with most Americans I've known.
I am probably misunderstanding what you say, but Cornet has grown up in France, and is probably very aware that health care cost in the US is not a normal thing since he comes from a country where it is considerably cheaper if not free.
His naiveté was about the nature of Google and how he thought a giant corporation basing their revenue on ads and collecting information could be a positive force in the world and not abuse its power. It seems to me his gripe is about the hypocrisy, which in a sense make it even harder to fix the company: if people denies the company ethics problems, you can be sure they are not going to get better.
Twitter in that sense has never promised to not be evil. You can't be naive about its ethics because you just have to doom-scroll the app for an hour to feel bad about it.
Trying to translate in French, I came up first with "Il eût fallu qu'elle eût été surveillée", but mostly because of morphological similarity (it's almost the same amount of verbs, right?). It's also just a more literary form of the simpler "Il aurait fallu qu'elle soit surveillée".
That being said, I have trouble to parse the original english sentence so I may be missing subtleties.
Obviously the primary intent was not loss of life. But there are multiple possible intents, one being obviously to instill fear: "We didn't kill you this time, but we totally could have". Imagine living in the area now.
Anyway, it's better to wait for more information than to speculate.
No known ancestor of Hitler is Jewish. His paternal grandfather is unknown, and that led some people to speculate that he was Jewish.
Hitler had his minions try to clear that up to dispel the rumours, but nobody could find the real father. They concluded of course that he was a pure Aryan.
