Like a movie, a person’s life consists of three acts. For most people, the third act is a simple continuation of the second, continuing to work in that same field, getting a promotion, or finally retiring. In rare cases, the third act  comes with a complete reversal where the person changes their behavior and thereby improves their life dramatically.

We may be living in the age of information, and the internet has almost everything at our fingertips, but sometimes finding the answers to our most burning questions can be harder than a simple Google search would first seem. We have trawled through the internet and found the answers to some of the most common questions where people wonder… is it possible? Can you actually cry blood? Is it possible to catch up on sleep? Join us below as we answer these and other questions that the internet has been wondering about.

As far as the universe can be said to exist at all, it probably has 10 dimensions. That’s the only way string theory makes sense. And physicists want string theory to make sense because it could be the Theory of Everything, uniting the otherwise incompatible theories of general relativity (for very big things) and quantum mechanics (for very small things) into one internally consistent package.

In the United States, 1 out of every 3 people has at least one tattoo. Clearly, the old-fashioned stigma that tattoos are part of a rough-and-tumble subculture has become a thing of the past. In fact, human beings have been decorating their bodies with permanent ink for thousands of years. Tattoos show up again and again across cultures and generations. There is something about getting a tattoo that is permanently apart of human nature. So then… why, exactly, do so many people want tattoos?

Today, pregnancy testing is incredibly easy and most people take it for granted, but not long ago in history, the pregnancy tests we have today were pretty much unheard of. People had to resort to… other methods. Going back to the days of the ancient world, women were just as excited about having answers to whether they were pregnant, but there really wasn’t anything in the way of a scientifically accurate test. For this reason, people have resorted to all kinds of zany methods, with varying levels of success.

Most things that are considered to be strange, dangerous, or offensive eventually become illegal at some point in time. However, there are a few things that are truly unsettling, and yet somehow, they are perfectly legal. Here are the top 10 outrageously strange things that are actually legal.

A trademark usually presents itself in the form of a name, a logo, a design, or a phrase, with the purpose of distinguishing one manufacturer’s products from another. Sometimes, however, when business is really good for a particular brand, or it has a head start over the competition, then that particular brand might just become a proprietary eponym, or generic trademark. This means that if a product develops a substantial market share over the other manufacturers, or it becomes well ingrained into the public consciousness, then its brand could replace the name for the entire industry.

In philosophy, determinists believe that free will is an illusion and that, therefore, human beings can’t be held morally responsible for their actions. As a result of nature and nurture, man’s actions are inevitable. Although he was unable to articulate determinists’ philosophy, HH Holmes believed that he was born to kill. He believed that he had no control over his actions whatsoever, and therefore would not even apologize for the lives that he claimed.

The FBI’s Behavioral Analysis Unit (BAU), was first formed in 1972 under the name the Behavioral Science Unit. The foundation of the unit was agents Robert Ressler and John Douglas. Ressler and Douglas wanted to bring in elements of psychology to help develop a profile of unidentified spree or serial killers, which they called Unknown Subjects, or UNSUBs. Ressler is also credited with coining the term “serial killer.”

He went on to invoke the legacy of explorer Francis Drake, and concluded by saying that the nation would never forget seeing the five crew members, the engineer, and the teacher, whom he dubbed the Challenger Seven, as they “slipped the surly bonds of earth to touch the face of God.” It was one of the most important speeches in modern American history. With that speech in mind, let’s remind ourselves of and learn more about this national tragedy.
