Each person responds to an emergency situation differently and a person can respond to emergency situation differently each time depending on the circumstance. I have know individuals in the rescue business for many years (including myself), who have performed some rescue or ems technique/procedure hundreds of times to the point it has become second nature, suddenly freeze and have to literally be talked through the event. No one knows for sure how they will react to a particular event. Training, knowledge and equipment will clearly be an advantage, but will not predict with absolute assurance how an individual will react. If, having words, photos or other comfort items will increase in a positive way, an individual’s response to an emergency go for it, we are all different and must find what will work for us. Pete
