The myth of the eight-hour sleep

The myth of the eight-hour sleep
Image copyright Other We often worry about lying awake in the middle of the night - but it could be good for you. A growing body of evidence from both science and history suggests that the eight-hour sleep may be unnatural. In the early 1990s, psychiatrist Thomas Wehr conducted an experiment in which a group of people were plunged into darkness for 14 hours every day for a month. It took some time for their sleep to regulate but by the fourth week the subjects had settled into a very distinct sleeping pattern. They slept first for four hours, then woke for one or two hours before falling into a second four-hour sleep. Though sleep scientists were impressed by the study, among the general public the idea that we must sleep for eight consecutive hours persists. In 2001, historian Roger Ekirch of Virginia Tech published a seminal paper, drawn from 16 years of research, revealing a wealth of historical evidence that humans used to sleep in two distinct chunks.

15 Years of Cutting-Edge Thinking on Understanding the Mind by Maria Popova What mirror neurons have to do with Abu Ghraib, the science of religion, and how happiness flourishes.

Nicola Tesla, Albert Einstein and Swami Vivekananda The Vedas are a collection of writings consisting of hymns, prayers, myths, historical accounting, dissertations on science, and the nature of reality, which date back at least 5,000 years.

But the whole reason for me publishing our case is that a person was badly injured the legal and judicial system had let the patient down severely, like a bird falling from the sky and left to die. Even though the claimant had a spouse but he was prevented from taking part in her claim, because the legal and judicial system was collaborating together in preventing the spouse and family in having any say in the outcome of the claim.

British have invaded nine out of ten countries - so look out Luxembourg The analysis is contained in a new book, All the Countries We've Ever Invaded: And the Few We Never Got Round To. Stuart Laycock, the author, has worked his way around the globe, through each country alphabetically, researching its history to establish whether, at any point, they have experienced an incursion by Britain. Only a comparatively small proportion of the total in Mr Laycock's list of invaded states actually formed an official part of the empire. The remainder have been included because the British were found to have achieved some sort of military presence in the territory – however transitory – either through force, the threat of force, negotiation or payment.
