The right to preventive health care.

The right to health care is a right to care that (a) is not too costly to the provider, considering the benefits it conveys, and (b) is effective in bringing about the level of health needed for a good human life, not necessarily the best health possible. These considerations suggest that, where possible, society has an obligation to provide preventive health care, which is both low cost and effective, and that health care regulations should promote citizens' engagement in reasonable preventive health care practices.
