Sleep paralysis occurs as a person is moving into or out of REM (rapid eye movement) sleep, the deepest part of sleep. During REM sleep, the body is largely disconnected from the brain, effectively leaving the body paralyzed.
England and a few other countries start formal education at age 4 or 5. That's harmful and misguided.
But vibrant societies have also recognized the place of a more structured, public system. In today's world, few people would question the need for a formal education system that is accessible for everyone. Formal education is central to the development of a nation. It is only through the implementation of a formal system of learning that any country can hope to develop a knowledgeable society and progress towards the achievement of societal goals. This conviction took a hold in Europe, Britain and in the United States during the 19th century, and it was during this period that the basic tenets of a formal learning system were established and developed. Social problems threatened to destroy the very fabric of society, and education was seen as a powerful solution.
