Anti-aging Ingredients: Anti-aging addresses how to prevent, slow, or reverse the effects of aging and help people live longer, healthier, happier lives. It includes scientific research and applications in genetic engineering, tissue engineering, and other medical advances.

The anti-aging marketplace includes nutrition, physical fitness, skin care, hormone replacements, vitamins, supplements, and herbs. Alternative medicine and holistic approaches have often been an incubator for approaches initially shunned by traditional medicine. Life extension is arguably the most scientifically rigorous part of anti-aging, being a research program focused on slowing down, repairing or reversing the underlying processes of biological senescence in order to deliver improved health and quality of life. (Despite the name, increasing mean or maximum lifespan is not necessarily the main goal).

Leading sources of anti-aging information include the Life Extension Foundation (focusing on research and supplements), the American Academy of Anti-Aging Medicine (focusing on anti-aging physicians and cutting edge treatments), Andrew Weil (focusing on alternative medicine, holistic health, and herbal supplements), the Chopra Center for Wellbeing (focusing on mind-body medicine and integrating Eastern and Western medicine), and the Ageless Lifestyles Institute (focusing on anti-aging psychology). In India, some anti-aging activities are studied by Center for Longevity combining western medical approaches with Siddha Vaidya nd Ayurveda.

Anti-aging pursuits date back at least to ancient Egypt. While the religion and pyramids focused on the afterlife, a lot of attention was given to herbs and remedies such as olive leaf to promote beauty and longevity. Over the centuries scientists and alchemists tried to find cures and potions. These included drinking, eating, or injecting substances such as gold, testicles, and transplanting monkey gonads. Many cultures such as India and China developed long traditions of herbs, foods, diets, and health practices to foster anti-aging.

There are many legends of magic places that give life, e.g., Ponce de León’s search for the "Fountain of Youth." In 1933 British novelist James Hilton’s book Lost Horizon described Shangri-la – an ageless paradise somewhere in the Himalayan mountains near the Tibet-China border. Despite Shangri-la being a fictional place, expeditions have tried to find it.

Gerontologists have tended to paint a bleak picture of aging being all downhill with increasing loss of skills, functions, and quality of life. Women’s movements leaders, e.g., Betty Friedan’s book The Fountain of Youth and books like Gail Sheehy’s Passages helped paint a more positive, generative template for aging.

Around 2000 research started identifying strengths that go with aging. Daniel Mroczek, Ph.D., found that older people report being happier than younger people. At ages 18–27 only 28% reported being very happy. The percentage goes up with each age bracket with the bracket 68-77 at 38%. The rating dips a little at ages 78–89 to 34%. Other researcher found that seniors tend to be better story tellers and become more agreeable and conscientious with age. Laura Carstensen, Ph.D reports that as we age, we are tend to be more positive and in better control of our emotions.
