A "life line" is a term often used to describe a crucial support system or resource that helps individuals navigate challenges in their lives. It can refer to emotional support from friends and family, professional help from therapists, or even community resources like hotlines and support groups. These connections provide guidance and assistance during difficult times. In a more literal sense, a life line can also refer to a physical line used in emergency situations, such as a rope thrown to someone in distress in water. This type of life line is essential for rescue operations, ensuring safety and saving lives when immediate help is needed.
