It is necessary for us to grasp some basic and practical first aid techniques in case some minor but dangerous incidents happen in our daily life.You may see someone bleeding£¬ getting an electric shock£¬collapsing suddenly or slipping carelessly in front of you. However urgent and desperate the situation seems£¬ never scream in panic. Offering timely first aid to victims without delay before the ambulance arrives is important because it can ease discomfort and sometimes may even save lives.For example£¬ when seeing someone choking on food£¬ you’re supposed tohelp him to his feet and slap him on the back to force out the obstruction.

Anyhow£¬ we can never justify sitting there and doing nothing£¬ since we all have a responsibility to look after one another’s welfare and any of us may be out of shape and need help some day.
