What's a deeply unsettling fact?

1. If you are a certain distance from a nuclear explosion, you won't be killed immediately but instead, you'll get third degree burns throughout your entire body. This kills your nerves so fast that it's completely painless.

2. I test schools' water for lead. Millions of children across the United States, many people here included, are being exposed to absurdly high levels of lead. This leads to behavior and learning problems, lower IQ, hyperactivity, slowed growth, hearing problems, and anemia. If not for yourself, for the sake of your children, please use filters at home.

4. There's now a strain of gonorrhoea which is [totally resistant to antibiotic treatment.](https://www.theguardian.com/society/2017/jul/07/untreatable-gonorrhoea-superbug-spreading-around-world-who-warns)

5. There are a huge amount of illnesses that aren't curable or even treatable. We have this idea that we go to a doctor, they find out what's wrong with us and then fix us. There are many illnesses that make doctors throw up their hands because they don't even know *what* is causing us to be unwell, and people are often ill for years, or life.

6. I wouldn’t call it deeply unsettling, but I’m disturbed by the fact that I only get a small amount of time to do stuff I think is worthwhile and figure out how this ant farm we live in works but every day I have to lie down and step outside existence for 6-8 hours. The world keeps going, I keep getting older, and yes, my brain is still processing things while I sleep, but I feel that it is a massive waste of time. If I don’t sleep then my mental and physical health start to decline. The process of falling asleep and waking up also disturbs the project or train of thought that was underway during the day requiring even more time to get back on track. Meanwhile dolphins are out there staying up 24/7 which is why they are smarter than us and will be leaving the planet first.

7. /u/KatamoriHUN already posted this, but there's more to the story. > If an asteroid happened to be on collision course with Earth, we can't really do anything against it. Not only this, but quite frequently we fail to notice asteroids that fly stupidly close to the Earth until after the fact. For example, in July an asteroid the size of a passenger jet passed by the Earth. We discovered it 3 days after it would have hit us, had it been on a collision course. Also, it passed by at a distance of 76k miles. That sounds like a lot, right? Well, that's only a third of the distance between the Earth and Moon.
