Question :Why, when we twist and turn in our sleep so much, is it rare that we fall of bed?
Answer: Even when you're asleep,your brains is still rare of its surroundings to some extent. It will have remembered how big your bed is and how far your body can safely turn. Should you get too close to the edge, your brain will tell your muscles, and you'll roll backward. Be warned, though: Your brain will often lose its bearing if you've been drinking or if you're in an unfamiliar bed.

Question: Why do we call illegal activity "bootlegging"?
Answer: The Oxford English Dictionary defines a "bootleg" as, perhaps obviously, the leg of a tall boot and says that from this arose the term "bootlegger" to describe someone who carries liquor in his boot-legs. It quotes a New York publication that printed, in 1980, "The 'Bot-legger' is a grim spectra. He is a man who wears boots in whose tops are concealed a flask or two of liquor."
The first reference to "bootleg" actually appeared a year earlier, when the Ohama Herald wrote, " There is as much whiskey consumed in Iowa now as there was before 'for medical purpose only,' and on the bootleg plan."
Today, the term refers to any item that is illicitly transported or produced, such as CDs.

Question: How do ancient ruins gets covered in so much earth?
Answer: You'd be surprised at how quickly earth can form. A neglected garden path become hidden in only a decade, so it's little wonder that archaeologists often have to dig metres down to find very old buildings. Earth is created as rocks in the ground are broken into smaller particles by weathering and erosion. The process is continued by plant decay and by worms, which convert organic matter to soil via their digestive systems. If a ruin is in a river valley or a typical field, where there are lots of plants and eroding water, soil could cover it in as little as a few hundred years.
