Dear Cristian, Very interesting read and even more impressive video! We indeed have to increase our efforts to promoting good health starting ofcourse with ourselves. As health professionals, we learn and discuss measures to preserve and promote life, however we do not always practice what we preach. With the increasing level of cardiovascular diseases globally, it is still a wonder that some health professionals do smoke. During my Master's program in Public health, a number of my coursemates smoked tobacco and drank excessively, immediately after lectures! So I always wondered what they said to their patients or other people who had unhealthy habits. Therefore, I think we should begin changing ourselves first and foremost and developing healthy lifestyles so that when we go about promoting health, we can do so confidently and others can see our lives as exemplar.
