$MASKS

A mask is a covering for the face or part of the face, worn for various reasons such as:

1. Protection: From dust, pollution, or airborne pathogens (e.g., surgical masks, respirators).
2. Disguise: To conceal one's identity or expression (e.g., Halloween masks, theatrical masks).
3. Cultural or spiritual significance: In some cultures, masks are worn for ceremonies, rituals, or to represent mythical figures.
4. Fashion or cosmetic purposes: To add a decorative element or alter one's appearance (e.g., Venetian masks, masquerade masks).
5. Medical or therapeutic purposes: To treat conditions like sleep apnea (e.g., CPAP masks) or to provide oxygen therapy.

Masks can be made from various materials, such as fabric, plastic, metal, or wood, and may have different designs, shapes, and sizes depending on their intended use.
