Puberty is a significant developmental stage marking the transition from childhood to adulthood. It's a time when the body undergoes various physical changes as it prepares for reproductive maturity. Typically, girls enter puberty earlier than boys, experiencing a range of changes that signify the beginning of their journey into adult life. The process involves hormonal shifts that result in growth spurts, the development of secondary sexual characteristics, and increased independence.

Following puberty, individuals enter adolescence, commonly known as the teenage years. This phase is characterised by rapid growth and psychological development, where teenagers explore their identity and independence. It's a time of life filled with significant milestones and transformations. In contrast, the term 'elderly' refers to those who are generally over the age of 70, and it is often suggested that an active lifestyle can contribute to a more fulfilling experience in these later years. Before these stages, during pregnancy, a human embryo is termed a foetus after eight weeks, continuing to develop until birth. The gestation period, which is the duration from conception to birth, typically lasts nine months in humans. Adulthood, the stage that follows adolescence, is commonly recognized from the age of 18, although legal definitions of this age can vary internationally. Adult life spans over several decades, encompassing maturity, aging, and the accumulation of life experiences.
