Monitor with giant cactus
Formerly, when still the CRT (Cathodic Ray Tube) monitors were in use, emerge the myth of cactus that absorb the monitor radiations.

 Logo of the Adobe Flash Player with a forbidden sign above it
Have you ever tried to watch a Youtube high definition video with a slow computer? If you didn't try it, I tell you that, regardless the charge time, it's played slower than a lame and asthmatic turtle. However, if in that same computer, you download the video and play it with a good video player like VLC, you can see it perfectly. Do you want to know why? Don't left of read the rest of "Why are the videos in Flash so slow?"
