David Sadtler is a career writer, teacher, and management consultant specialising in corporate strategy and finance. He has published a number of books and many articles on these subjects. Although still counselling on several investment projects, he has increasingly focused his concern and attention on social issues, and in particular on obesity, since it is becoming the leading public health problem worldwide. The subject of deference and the damage it can do has also caught his attention. His latest area of interest is the Catholic Church and its problems as it faces the uncertain prospect of a new Papacy.He can be contacted at david.sadtler@gmail.com and would welcome your comments.
