Dr. Bill Andrews is the Founder and CEO of Sierra Sciences, a company focused on finding ways to extend human lifespan and health span through telomere maintenance. Telomeres are found at the tips of our chromosomes and have been shown, in thousands of scientific peer-reviewed studies, to be the clock of aging in humans. When telomeres get shorter, we get older, and our health declines. As a scientist, athlete, and executive, Bill continually pushes the envelope and challenges convention. He has been featured in Popular Science, The Today Show, and numerous documentaries on the topic of life extension including, most recently, the movie The Immortalists in which he co-stars with Dr. Aubrey de Grey. See www.theimmortalists.com/watch. Bill is known for being a scientist first, focusing on scientific research, allowing others, instead, to market the products that his company discovers.
