It is funny to think of fish sleeping but they do. All animals need to sleep to stay healthy. They sleep when they need to but also it depends on whether they are nocturnal or diurnal. Fish do not have eyelids so they are thought to be resting. They can see when sleeping and can be immediately alert to any dangers. When you see fish being inactive or staying in one spot they are usually resting/sleeping. It is a good idea to shut any lights off to give them the darkness they need. They sleep part of everyday asleep if the conditions are right.
Fish are different in that part of their brain actually shuts down and they lightly rest. They are in constant movement so that they can take oxygen in through their gills and into their bloodstream. It is amazing that some fish actually go into hibernation. When they do this, their metabolic rate slows down. They are not like bears or other mammals. They go into a kind of daze and stop eating. They usually hide at the bottom of the tank or near rocks etc.
Some fish go through a completely detailed event when sleeping. One such fish is called a Parrotfish. They live near reefs that they squeeze into. Once in the there they produce a mucous substance that covers their body in a protective membrane and then they go to sleep. Through research not only has it been found that fish sleep but they can also suffer from sleep deprivation and insomnia just like us. They never reach the REM sleep as we do. I guess if you were a fish, you would not want to be in a deep sleep. You may end up on a hook!
A clock is an instrument that indicates and maintains time and passage. Before clocks were established, the terms “sun wise” and “deiseil” were used. The earliest form of time keeping dates back to 3500 B.C. These words are from the Scottish Gaelic. They refer to the direction of the clocks hands. Have you ever wondered why clocks run clockwise? The definition of clockwise is the same direction as the hands of a clock. Well that makes sense. It may seem like a funny question but let us explore it. Inventors who were trying to make models of the suns movement in the sky invented clocks in the northern hemisphere. Today this region is actually Iraq! To watch the sun from this hemisphere you have to face south.
Therefore, the sun would rise on your left and pass over your head to set on the left. Therefore, the hands of the clock were designed to move left to right over the clock clockwise. The hands were modeled after the design of a sundial-(a vertical stick or obelisk). It is described as a tall four-sided shaft of stone that casts as shadow. This is how people used to tell time. You can find one in Jantar Mantar in Delhi. We actually did not have watches until the early 20th century. Throughout history, the movement of the earth around the sun determined time. It seems this movement is by accident as to where people settled and human nature. If so, long ago our ancestors had decided to settle in another place like Africa, we would be dealing with a counter clockwise movement. This is because everything is reversed south of the border.
Long time ago people realized that the earth revolved around the sun so they knew when the sun was in a certain position what time it was. You probably are familiar with the notion that when the sun is highest in the sky it is close to noon. Clocks were not invented until 100 A.D. in China. It is surreal to think that if we were in a different hemisphere we would read out clocks and watches differently. If clocks were invented in the southern hemisphere instead of the northern hemisphere, we would be watching the hands of our watches go from right to left! That is weird to think that things could have been so different. In fact, some Arabic and Jewish clocks run right to left but then there lettering reads from right to left too.
Therefore, I hope this helps to inform you about the movement of clocks. It is fascinating to know and the history of clocks and little known gems of facts.
Sordid tales about vampire is a word out of literary imagination than fact of any significance. Vampire is by itself a sordid tale of ghosts, werewolves, tales of horror and unsolved mystery etc. Vampire assumes the form of a woman or a big bat or a man with a penchant for human blood as in the case of count of Dracula. Dracula is the fictional character out of imagination depicted as an example of a human vampire. He was a creation by Bram Stoker, a horror story writer and become popular for the work. The narration of the story in movie makes women faint.
Now it is proved by the scientists that these dangerous creatures do exist in the form of bats and humans but with a twist. A case of a woman Anastasie Dieudonne in Haiti, confessed to sucking the blood of her niece driven by an urge absolutely uncontrollable with a mental imbalance. This is the case of a human vampire. There have been many cases reported similar to this from different walks of life more dramatic and horrifying.
With reference to bat vampires, Dr. August Kronheit of the German Academy of Science, and member of a number of leading American societies, has made an elaborate study of them in South America. Dr. August Kronheit of the German Academy of Science has done a in-depth research on the existence of bat vampires in south America. He identifies the true vampire as a monster natured black-brown bat with a large wing spread and razor-sharp teeth with easily unrecognizable nose resembling a pig. As a bat, it is nocturnal and sucks blood by attacking animals and humans at sleep. A case of a young girl in Bolivia proves this case when the girl’s dad saw a bat crouching on his daughter’s shoulder at night in the porch. He crushed it to death and later found that the vampire was sucking blood from the girl.
This is not to frighten the readers as most of the bats are harmless. They live by eating insects or by sucking juices from fruits. Vampire bats are known to exist in tropical countries. The puzzling fact is that the victims are not awakened during sucking of blood by the vampire. Reason is attributed to the flat razor-sharp teeth that shave the upper portion of the skin. Blood is sucked through the abrasion by suction. It is neither biting nor stinging and has no depth and so the wound created doesn’t create any pain for the victim. Human vampires are psychologically affected people with a passion for sucking human blood and investigations do point out that such people existed earlier and exist now also.
