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.
A Look at the Education System. The education before 6 years is termed as pre-primary education or kindergarten education and is divided into two groups. First is up to 3 years and the second is from 3 to 6 years of age. From 6 to 16 years of age, the education in Spain is divided into two groups. 1) The first group, called primary education, is for students between the ages of 6 and 12. 2) 12 to 16 years ( called secondary education) The primary education is divided into three cycles 1) 6 to 8 years (first cycle) 2) 8 to 10 years (second cycle) 3) 10 to 12 years (third cycle) During this stage, the average number of students in a class is around 25 in the Spanish schools.
