The Norman Cousins column ("Let Wisdom of the Body Promote Natural Health" Op-Ed, Feb. 1) identifies many socio-cultural factors involved in making up the attitudes towards health and disease in this country. Changing these factors will be difficult. On an individual level, people don't seem to be willing to spend the time needed to take care of their health. Yet I see many Los Angeles residents spending lots of time and money on car maintenance. They spend hours a day watching expensive TVs and VCRs. If they would only make the same investment in themselves.
