Competing Interests

Elissa Epel, PhD; Elizabeth Blackburn, PhD; and Jue Lin, PhD are the co-founders of Telome Health, a company focused on telomere length biology. The company has a product that provides researchers with an assay service for telomere length measurements from samples of human DNA, as part of clinical and other research studies. The product is based off the “Cawthon qPCR assay,” and Telome Health has the rights to the patent on this technology. Telome Health does not have any other patents. The authors' involvement in Telome Health does not alter their adherence to all the PLoS ONE policies on sharing data and materials. Jeffrey Krauss; Ramin Farzaneh-Far, MD, MAS; Beeya Na, MPH; Eli Puterman, PhD; and Mary Whooley, MD, have no relevant financial interest in the manuscript and declare that they have no other competing interests.
