The term 'HELP FROM A LIFEGUARD' can be broken down into four words, each with four letters. The first word is 'LINE', which refers to the LINE of demarcation between the shallow and deep ends of a swimming pool. A lifeguard is responsible for monitoring the swimmers in the pool and ensuring that they stay within the designated area. They also provide assistance to swimmers in distress, such as rescuing them from the water or providing medical attention. In addition, lifeguards are trained to provide first aid and CPR in case of an emergency.
