Abnormal posturing is different from bad posture or slouching.. Instead, it involves holding a body position, or moving one or more parts of the body in a certain way. Abnormal posturing may be a sign of certain injuries to the brain or spinal cord.
Follow @TIME. 1963 was a momentous year in America: President John F. Kennedy was assassinated, Martin Luther King Jr. delivered his âI Have a Dreamâ speech at the March on Washington and, somewhat less heralded by all but the most fervent postal historians, the ZIP code was introduced.
Using area codes to help efficiently sort post was introduced in 1943. 1950's a more specific and detailed guide was needed. This is when the United States Postal Service began using the ZIP code (ZIP meaning Zone Improvement Plan). It was first thought of by postal inspector Robert Moon - he submitted the proposal for a ZIP code in 1944. However, his idea was largely ignored until the 1960's. The ZIP code began to be used widely in 1963.When did we start using zip codes? Area codes? In addition to what Milson Bartleby said above, I'll point out that, in an effort to increase efficiency, the U.S. Postal Service began using the ZIP + four system in 1983.
