Age is the period of time that has elapsed since the creation of something. The most common use of the term is to indicate the life span of a living creature.
Human life is conceptualized into several parts, determined by age: infancy, childhood, adolescence, maturity, menopause in men or menopause in women and old age; However, there are no exact ages that define the transition from one age group to another.
The age in the culture
In Western culture it is common for the age of man to be counted as the amount of time that passed from birth until a certain point in time, when the year is rounded down. The Bible and Chazal were usually rounded upwards. However, in East Asian cultures the age can be excellent in the method in which a person's age is considered to be one (and not zero), and the person's age grows each year when a new year begins in the calendar (whether it is the Gregorian calendar or traditional or local calendar). This method can lead to a difference of 2 years of counting versus the common method in the West.
A person's birthday is the day of the year in which the date is the same as that person's date of birth. On this day his age was measured in whole years. This day is generally considered a happy day and celebrated by the person in the company of his family and friends.
Some people, especially women, do not publicly disclose their age.
In different cultures, different rites of passage mark the passage from one lifetime to the next.

Age in legislation
In most countries, the law recognizes several age groups, and different rights or restrictions apply to the citizen according to his or her age.
Longevity
Longevity is a term that refers to the upper level of human life expectancy. This is a cultural and medical concept, for example in adventure books, science fiction and Utopian novels. Myths about longevity also exist in the present. However, there is a great difficulty in verifying the longest human life ever, due to lack of registration, documentation and time measurements in the past and careful lip or cultural gaps. The oldest person whose age has been verified is the Frenchman Jean-Louise Clement, who passed away in 1997 at the age of 122 years and 164 days.
Over the years, the possibility of reaching a very old age has fascinated many people. Many organizations are dedicated to investigating the causes of aging, ways to prevent aging, and ways to reverse aging. Some see it as a trance humanism and pursue immortality (for example, the Raleigh sect). On the other hand, there are organizations that oppose "anti-aging," arguing that it is not natural or moral.
The ages of animals
The life span (maximum age) of different animals varies among species. The animals with the shortest life live a few days, while several species of animals can reach the age of many tens of years. The longest-lived animal known to science is Greenland shark.
Turtles are known for their long life span. Some species live longer than almost any other creature in the animal kingdom, sometimes even centuries. According to the Science Department of the New York Times, their organs are not aging, unlike most if not all other animals. In March 2006, for example, he died at the Kolkata Zoo, India, a 250-year-old giant turtle. Scientists claim that there are turtles, which in the absence of disease or injury can live forever. Only the lobsters and the "immortal Jellyfish" Turritopsis dohrnii, and perhaps one or two other species of rare animals compete with tortoises of their potential lifespan.
The ages of plants
Many plant species are annual, meaning they reach a maximum age of one year, and then another individual grows in their place. Different types of trees, on the other hand, may reach very young ages; Trees whose age is measured in thousands of years are known. Among these trees are certain species of pine trees, cypress trees, and ginkgo trees. Assessing the age of trees is done by counting rings within their own .
