In general, I’ve found that people are very slow to change what they do if they change at all. No matter how many facts, charts and reports you show, many/most people will not heed the advice. This is true with many different things in life. For instance, most smokers, drinkers, criminals and drug addicts won’t kick their habits when faced with facts. Instead they choose to die or go to jail rather than change their ways. Another example is countless millions of people are overweight and unhealthy from not eating correctly. Most of them will not listen to common sense advice about healthy eating.
