Age Categories

Throughout our life, we undergo some serious changes, which happen in physical, biological, mental, emotional, and other levels, as well as accompany us throughout our lives, from our early childhood to our final moment. Specialists define a number of age categories which every individual goes through. There are different approaches to the classification, but all of them can be generally represented as the following.


Infancy is the first age category and includes 0 to 2-year-olds. This is the stage when a baby develops all his body organs, as well as starts mastering the first motor skills, discovering his own physical power, experiencing and developing his sensory abilities, etc.


Childhood is the second age category, which takes place between 2 and 9 years. During this life stage, a child experiences really fast growth and plenty of developments, starting from learning to speak, to read and to write, and ending up with mastering some first social skills and feelings.


Adolescence, or teenage-hood, is the third age category and is considered as one of the most difficult life stages. The age category includes young people between 10 and 19 years old. This is the time when fast growth and development continues, and the person experiences puberty, serious hormonal changes, along with new and very strong emotional and social experiences. This is the life stage when young people discover most sides of this life and try to understand what this world is all about.


Early Adulthood is the age category which includes 20-29 year-olds. People in this category continue and complete their education, start their professional career, and most of the people start their families and possibly have children. In early adulthood, people learn to be independent, organized, responsible for their families, and useful for society.


Adulthood is the next age category, which involves the people of 30-39 years old. At this life stage, people are usually very active in their personal, social, and business life, with the most of efforts spent for raising their families, developing their career and coping with minor daily problems.


Middle Age is the age category which includes the people achieved the age of 40, and it lasts till the age of 59. This is one of the most enjoyable but at the same time, one of the hardest life stages since the people start experiencing the first signs of aging and physical inabilities, which can affect their emotional condition to a great extent. In addition, such factors as loss of their parents or their children leaving their nest can bring to more serious emotional problems.


Early Elder is the age category which includes people who are 60-80 years old. This is the stage when aging starts affecting the lifestyle of people. Emotional instability and stresses can be caused by such factors as retirement, increasing health problems, possible need to be looked after, etc.
