    مراحل الحياة
    The stages of life


    From infancy to the senior years, humans physically mature at different paces but in distinct phases of development. .


    Infancy
    From birth to age 2, humans develop muscle strength and nervous system control. Infants start with the ability to focus their eyes, then develop verbal communication skills and usually take their first steps around age 1. During this time, their digestive system begins to process solid and complex foods. By age 2, their vocabulary may include as many as 200 words.


    Childhood
    As toddlers, humans develop a sense of humor along with their emerging sense of identity and self-expression. During the preschool years, children further develop their motor skills to include running, jumping and balancing on one leg. After age 5, children have more developed social lives, they learn to read and write and have a vocabulary of more than 2,000 words. Physically, they have better balance and smoother muscle coordination. At the onset of puberty, usually between the ages of 8 and 13, they move into adolescence with the development of genital organs and characteristics


    Adolescence
    Adolescence, the transition from childhood to adulthood, begins around age 13. Adolescents have an improved ability of self-expression but may have difficulty refining a self-identity and controlling their emotions and impulses. They can work for longer amounts of time on more difficult tasks than when they were children. They experience rapid growth and weight gain due to puberty, as well as hormonal changes that can lead to acne and a change in voice.


    Young adulthood
    A person reaches physical maturity and stops growing around age 18. As early as age 20, people may notice the beginning signs of aging: fine wrinkles, thinning skin, loss of firmness in hands and neck, graying hair, hair loss and thinning nails. At age 30, the human body's major organs begin to decline. According to the American Federation for Aging Research, cognitive abilities seem to be at their peak starting between ages 30 and 40.


    Middle adulthood
    After age 40, metabolism slows down and skin and hair may show more signs of aging. Starting at 40, people should begin annual tests such as screening for colon and breast cancer. Muscle strength decreases between the ages of 40 and 65, vision and hearing diminish and bones become weaker. Women especially begin to lose bone density in the years before menopause, which usually occurs in the 50s. People in their late 50s and early 60s will experience a small degree of declining cognitive abilities.


    Senior adulthood
    Advanced signs of aging, including less skin elasticity, are apparent in adults over age 65. Arthritis and osteoporosis affect the joints and bones of many senior citizens, and other chronic conditions such as heart disease and cancer exact a heavy toll on the quality of life and cost of health care. Some people live to be well over 100 years old, but life expectancy, according to the CDC, is around 77.6 years in the United States.
