Readability is the ease with which a reader can understand a written text. In most situations, writers aim for high readability scores ensuring easy comprehension by the masses. To measure the readability of their works, writers employ tools like the Flesch-Kincaid readability test , which is a linear relation involving average sentence length and average word lengths. This algorithm produces a (mostly) positive score; the higher the score, the higher the readability . Note that, however, this method does not cover the syntax, complexity, and typographic aspects of the article. So, it's a good starting indicator but not a comprehensive one .
Most of us sleep in a single six to nine-hour stretch - monophasic sleep . Polyphasic Sleep seems to be a viable alternative to some athletes and productivity freaks, which mostly consists of one long sleep of a few hours and several shorter sleep periods . Babies and pets commonly practice this form of sleep. While polyphasic sleep might work for certain specific situations or groups of people by making sleep deeper and hence more productive, it is generally not advisable for students or employees. This is because its improper practice can lead to sleep deprivation, irritability, and general fatigue .
