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.
Further education (FE) is used to describe the education that occurs following compulory post-16 secondary education, which is usually distinct from that offered in universities (higher education). It includes many different levels such as A Levels and Higher National Diplomas.
