Cartilage is present in the joints of our body, which helps in their smooth movement. With advancing age, this cartilage wears off. How would this affect the movement of joints?

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Cartilage**: Cartilage is a flexible connective tissue found in various parts of the body, including the joints. It acts as a cushion between the bones, allowing for smooth movement.

2. **Role of Cartilage in Joint Movement**: The primary function of cartilage in the joints is to reduce friction between the bones during movement. This reduction in friction is crucial for allowing the joints to move smoothly without causing damage to the bones.

3. **Effect of Aging on Cartilage**: As a person ages, the cartilage in their joints can wear off or degenerate. This wearing off means that there is less cartilage to cushion the bones.
