[?] What is a thought virus? You can call it a meme or an idea that replicates by symbiotically infecting human minds and altering their behavior, causing them to propagate the meme. Our society have always been buzing with these meme around through communication. You might be thinking that a meme is a bad thing, from its association with a virus right?! Nope, it can be a good thing too, like an anti-smoking or anti-terrorism slogan. There are many kind of them "fizzling" in the air. The computer screen you are now staring at is blasting thousands of memes rockets at you! (yeap, they are like living organisms!) There are BILLIONS of meme specieS and BILLIONS of their various effects (some are crawling & controlling your SuperBrain )!!! Can you find any common species of meme around you or any Highly Destructive or Harmful Meme existing??
