Understanding the biology of aging is essential if we want to rejuvenate aged organs and tissues.

A Knowledge Hub for Aging and Longevity

As part of our commitment to education our goal is to share evidence-based knowledge about aging and rejuvenation among the general public, the business sector, policymakers, and philanthropists. To achieve this goal we have created an educational hub to help our readers learn more about the biology of aging. Here you can find a range of topics covering the biology of aging and other related subjects.

If you are new to the topic, we recommend starting with the basics and reading our pages about why we age and what is life extension.
