The answer to this question depends on what you mean by "fully grown."
Physical Maturity
- Physically: Most people reach their full adult height by age 17. However, some individuals may continue to grow slightly into their early twenties.
- Puberty: Most people complete puberty by age 17, which is a significant milestone in physical development. This means they have reached their full reproductive capacity.
Mental and Emotional Maturity
- Mental and emotional maturity: While physical growth typically ends around 17, mental and emotional maturity continue to develop throughout adolescence and young adulthood. This process can vary greatly from person to person.
Legal and Social Maturity
- Legal maturity: In most countries, individuals are considered adults at age 18. This means they have the legal right to vote, drink alcohol, and enter into contracts.
- Social maturity: This is a subjective concept that varies depending on cultural norms and individual experiences. Some people may consider themselves fully grown at 17, while others may feel like they are still developing.
In summary, while individuals may be physically mature at 17, mental, emotional, legal, and social maturity continue to develop throughout life.
