Youth and age: a collection of quotations

Around the world, the English terms youth, adolescent, teenager, kid, and young person are interchanged, often meaning the same thing, but they are occasionally differentiated. Youth can refer to the entire time of life when one is young, including childhood, but often refers specifically to the time of life that is neither childhood nor adulthood but rather somewhere in between. Middle age is the period of age beyond young adulthood but before the onset of various attempts have been made to define this age, which is around the third quarter of the average life span of human beings. According to Collins Dictionary, this is usually considered to occur approximately between the ages of 40 and 60. The current edition of the Oxford English Dictionary gives a similar definition but with a shorter span: The period of life between young adulthood and old age.
