How Much Fake Blood Has the Horror Movie Industry Used?
Answer by Kynan Eng, who specializes in tech startups and research, neuromorphic engineering, mobile big data, and VR:
My best guess is that 619,920 liters of fake blood (around one-fourth of an Olympic swimming pool) have been used in the production of “proper” horror movies—ones that had a commercial release. This is based on 17,712 horror movies, 5 liters of blood per horror scene, five horror scenes per movie, plus two scenes requiring blood for set-dressing. Note that these numbers don’t include movies with lots of blood but no horrror categorization, such as 300, Death Race, or Rambo.
How Can You Succeed at Learning Higher Math as an Adult?
Answer by Dmitriy Genzel, computer science Ph.D.:
Usually the problem that people like you have is that they got lost at some point in their education. Usually it isn’t at the level of the last class you completed, but somewhere earlier. We all use our intuition to do math. You can learn the rules, but if you don’t understand what they are for and why they are the way they are, you are limiting what you can learn. The rules are like training wheels on a bike, and as you get to the next level, your instructor assumes you know how to bike, and then you crash.
What’s It Like to Airbnb-Hop Instead of Renting an Apartment?
Answer by James Altucher, author, entrepreneur, and Wall Street investor:
For a year I’ve mostly lived in Airbnbs. I decided my life needed a purge. I don’t know why I felt this way—probably a combination of a lot of things. It wasn’t a consistent life strategy. It’s just something I did. I threw everything out, I didn’t renew two apartments I was renting, and I didn’t start renting anyplace new. I had no place to live.
Why Is It Offensive to Tell Someone He or She Looks Tired?

Does Tennis Equipment Need to Be Tweaked at Different Temperatures?
Answer by Laurence Shanet, former college/satellite tennis player, tennis coach, USRSA certified stringer:
For a recreational player, there is little need to tweak your existing equipment. Contrary to what many players will tell you, research has shown that even fairly high-level players can’t distinguish string tension differences of up to 10 pounds when using blinded conditions.

How Much of a Pilot’s Training Is Emergency Landing Practices?
Answer by Stan Greenspan, licensed private pilot:
You can teach anyone to fly straight and level in about 10 seconds. Push the wheel or stick forward, and the ground gets bigger. Pull the wheel or stick back, and the sky gets bigger. Turn or push right, you turn right; turn or push left, you turn left. Congrats, you can fly straight and level. It takes about 10 brain cells to do this, so you can do everything else while you fly straight and level.
Can People Become Force-Sensitive in the Star Wars Universe?

Why Was Darth Vader So Much More Powerful in Rogue One?
Answer by Rob Fletcher, Star Wars geek:
Because in Rogue One he benefited from 21st-century special effects and the weight of expectation brought by almost 40 years of being the most iconic villain in movie history, while in Star Wars he was in a cheap sci-fi flick nobody expected to be a hit and trying not to break the flimsy lightsaber prop.
How Does the Secret Service Adapt to Different Presidents?
Answer by Jason Wells, former U.S. Secret Service agent:
The Secret Service has learned a lot since they lost President Kennedy. Yes, it was their fault. They were responsible for President Kennedy’s life, and they did not appropriately secure the area that he was visiting. The result was one of the most politically changing moments in our country’s history and the loss of one the United States’ most popular presidents.
