According to Mayo Clinic, Down syndrome causes a distinct facial appearance, intellectual disability, developmental delays, and may be associated with thyroid or heart disease in a person. So calling people with this syndrome 'Mongoloid' is extremely vulgar and disrespectful to ethnic Mongolians. Likewise, how will the population react if Down Syndrome was associated with 'European' looks? If you use this term, you are automatically a xenophobic, in my opinion.
An ERA is a long period of history with distinct characteristics. For example, the roman era. A PERIOD is less distinct and defined, it simply represents a portion of time, be it a very short portion, or a very long portion. For example, my period of sadness and the jurassic period. An EON is an actual unit of time. 1 eon = 1 billion years. This is also used rhetorically to symbolize a long long time. For example, man! my new iphone took like an eon to arrive in the mail! or also more appropriately the earth is 4.5 eons old.
âBabies who are born prematurely often have two ages: Chronological age is the age of the baby from the day of birthâthe number of days, weeks or years old the baby actually has been in the outside world. Adjusted age is the developmental age of the baby based on his due date. To calculate adjusted age, you take your premature babyâs chronological age (for example, 20 weeks) and subtract the number of weeks premature the baby was (born 6 weeks early). In this example, the babyâs adjusted age would be 14 weeks.
