Final answer:
Agility indeed includes being quick, graceful, and nimble, and ballroom dancing can enhance these attributes along with balance and speed. Being accurate in describing the benefits of such activities is important for clarity and understanding.
Step-by-step explanation:
Agility refers to your body's ability to be quick, graceful, and nimble, and this statement is true. It involves a combination of balance, speed, strength, and coordination. For example, ballroom dancing is an activity that can notably increase agility. When discussing the benefits of activities like ballroom dancing, it is important to be precise in our language.
Instead of saying 'learning to ballroom dance increases agility and lengthens life,' we could more correctly say, 'Participating in ballroom dancing can enhance agility and may contribute to a longer lifespan.' Such activities can help in improving not just physical attributes like balance and motor skills, but also in developing kinesthetic awareness which is essential for activities that require body awareness and the ability to adapt to new movements and challenges.
