People used to believe that a murder victim's body would start bleeding when the killer was near.

It was called cruentation, and it was a medieval method of finding a suspected killer! It was part of Germanic law and used in North America, Germany, Poland, Bohemia, and Scotland. In trials or situations where it was difficult to say whether or not someone was guilty, cruentation was used.

The defendant would be brought in front of the murder victim and forced to lay hands on the body. If the body began to bleed from its wounds or show other odd signs, then it was believed to be God’s way of showing the defendant was guilty.

A species of spider breaks off its own penis to avoid being eaten by the female during sex!

The orb-web spider Nephilengys malabarensis has a very aggressive female. It's reported that in 75% of the cases, they kill and eat the male during sex.

As a precautionary measure, the males have developed a simple, but painful strategy. They break off their genitals. They remain attached to the female and keep pumping his seed. 

The males aren't able to regrow anything. However, they ensure that no other males can mate with the female. They become better fighters and most importantly, they stay alive!

One of the world’s first hackers used Morse code insults to diss the telegraph a century ago!

In 1903, physicist John Ambrose Fleming showcased a new type of communication system that would send Morse code through long distances. Right before he began the demonstration, though, the apparatus began to tap and wrote insults about Guglielmo Marconi, its inventor.

The point of the hack was to show the public that the apparatus wasn’t near as secure as Marconi had led the public to believe. The hacker was Nevil Maskelyne, a British music hall magician who had great interest in wireless technology and came from an inventive family.

Marconi had broad patents making it hard for Maskelyne to do much with wireless technology himself. Instead, he got even with Marconi by embarrassing him and his hackable apparatus.

Oral sex can help lower blood pressure!

It is unclear whether sexual activity makes us healthier or if healthier people have more sexual activity. None the less, research is showing that sex has great health benefits, when in the context of healthy, monogamous relationships.

Sex can ease depression and stress. Orgasms can be a great pain reliever, because they release oxytocin into the body. It can boost cardio health and fight aging. Remember, though, this does not count in risky sexual behavior, but in monogamous and stable relationships.

The towns of Silent Hill and Arkham Asylum are based on real places!

Arkham Asylum is designed after a turn of the century insane asylum in Arkham, Massachusetts. The creepy, labyrinth-like hallways and patient rooms are sketched from the real deal. The Arkham Asylum comes for Batman and D.C. comic video games.

Silent Hill is an abandoned town that always has fog or mist covering it. It’s been made popular by video games and movies. It’s based on an old mining town called Centralia, Pennsylvania. The mine caught fire and the town was evacuated. Five decades later and the fire is still burning! The town of Centralia has sink holes and steam pits all over it! Check out a video of people going through the town below
