If the population is not healthy, need of the high risk approach is essential. That means, for instance, that myocardial infarction and stroke patients need organized care and rehabilitation. That is what is classical medicine. This actually keeps doctors involved and interested in the activities, because they are trained for diagnosing and treatment of patients. There is also one very important topic related to benefits of high risk approach.
Patients are actually the tools for population approach.
For instance, if one family member becomes sick, actually even though that individual is concerned and is willing to change lifestyle, in many cases the whole family is willing to adapt new lifestyle.

There are societies which have, for instance, quite many voluntary and non-governmental organizations. These are just waiting for new ideas to incorporate them in their activities. They are also willing to cooperate and collaborate with the experts.
