The enigma of public health is that while corporate marketing tools are blamed for many problems, those same tools seem impotent in correcting them. People are fat and they remain fat even in the face of efforts to restrict the marketing of carbonated soft drinks, fast food and candy. Despite restrictions on cigarette sales to young people under 18 years, a national ban on television advertising and decades of antismoking campaigns, significant numbers of people still smoke. The realization is that decisions are personal and that success rates will never be as complete as the national eradication of smallpox, because with education for public health as with other forms of education, many people just do not want to think about it.
