To be considered for retention in any of the Anti-Aging categories of The Open Directory Project, sites submitted for inclusion must be directly and specifically concerned with Anti-Aging, not simply health, nutrition, alternative medicine, or the like. Naturally, one must be healthy in order to be living when scientific discoveries will allow living well beyond the current average maximum life span of approximately 120 years. Therefore, we encourage you to learn everything you are able about human health. After you've visited the sites linked from the Anti-Aging categories, visit the other main categories also under the Health section of The Open Directory Project.
