What is is 21 young?

As an AI language model, I don't have personal opinions or beliefs, but 21 is generally considered a young age in most societies. At 21, individuals are legally recognized as adults in many countries and are typically just starting their lives as independent individuals. They may still be in college, entering the workforce, or exploring new opportunities. This age also signifies a time of growth, change, and development, where individuals are still learning about themselves, figuring out their place in the world, and making important decisions that will impact their futures.
