Recognizing People Without Sight

People who cannot see have developed various ways to recognize the people around them. While they may not be able to rely on visual cues like facial features or body language, they can use their other senses to identify individuals. Two primary senses that blind individuals use to recognize people are smell and sound.

Using Smell
- Blind individuals can often identify people by their unique body odor or the scent of their perfume or cologne.
- Each person has a distinct smell due to their body chemistry, hygiene habits, and the products they use. Blind individuals can become familiar with these scents and associate them with specific individuals.
- Smell can also provide information about a person's surroundings. For example, the smell of freshly brewed coffee may indicate that someone is nearby.

Using Sound
- Blind individuals can recognize people by the sound they make as they move. Each person has a unique way of walking, which produces distinct footsteps.
- By paying attention to the rhythm, pace, and sound of footsteps, blind individuals can identify someone they are familiar with.
- Additionally, blind individuals can recognize people by the sound of their voice. Familiar voices are easily distinguished, and blind individuals can develop a mental map of their surroundings based on the direction and distance of voices.

Combining Smell and Sound
- Blind individuals often rely on both smell and sound together to recognize people accurately.
- By combining the scent and the sound of someone's presence, blind individuals can form a more comprehensive and reliable identification.
- For example, they may recognize a familiar scent and simultaneously hear the footsteps of that person approaching.

Conclusion
The correct answer to the question is option 'B' - blind individuals recognize people around them from the sound they make as they move. While smell also plays a role in identification, sound is particularly important in distinguishing individuals based on their unique footsteps and voices. Combining both senses allows blind individuals to recognize people with greater accuracy and confidence.
