Rob Gentile had a massive heart attack and near death experience. During those near death experience, he had an encounter with his brother in law, Frosty.
When he returned to a conscious state, he excitedly told hos wife about what he had seen. Following the heart attack, his heart grew weaker and he soon found himself fighting for his life.
He then had another near death experience and learned more about himself and the afterlife.
Fortunately, he received a donor heart and returned to his life of working and caring for his daughter. But, he also felt that he needed to tell people about what he had experienced. So for three years he got up early before starting his day and wrote about it.
