Where did the myth that police have to tell you they're police if you ask them come from? | Police are allowed to commit a very large variety of activities that would otherwise be considered crimes. The need to maintain cover is huge. They can move drugs, smuggle them. Launder money, as long as they are doing it within the scope of their undercover operation. They can do drugs if it's required to maintain cov... |
What is the "Faerie" lifestyle? | Bro from one man to another, bail. You're heading down a rabbit hole you don't want to go down. To answer your question, your friend is what is known as an "otherkin". Popular among Tumblr users, it's a term used to describe people who really truly believe they are not human, at least on the inside. Most people use it ... |
How do LiDAR sensors work? Wouldn't they just be overwhelmed by all the natural light? | They use very bright IR lasers, which you can't see because they're outside the visible spectrum. The LIDAR can easily see the spot from its laser - it's no different than using a [bright laser pointer].

Why are no countries boycotting the 2022 FIFA World Cup despite the corruption and even though people were exploited and died building the stadiums? | Because everyone still loves the World Cup.

Countries like NZ often have to wait to see movies months after they screen in the US and this provides a window for piracy that can't be closed by lawyers. If they release movies in non-US countries first then they only have to worry about piracy in the US and that's a scenario... |
What is a Physician Assistant (PA) compared to a doctor or nurse? | A PA, or a Nurse-Practitioner is somewhere between a nurse and a doctor in terms of training and education. For a lot of the things you typically go see a doctor for - strep throat, cold/flu, ear/sinus infection, pink eye, bronchitis, etc - you really don't need someone with 10 years of medical training to diagnose and... |
When we have those dreams that we're falling, why does it feel like we actually fall into the bed? | It's because when you're muscles are relaxed, sometimes the brain messes up and thinks that relaxed muscles mean you're falling instead of resting", 'I know this is odd, but the sensation of falling is all in your head.
