Studying van Andel-Schipper's body after her death in 2005, Henne Holstege, a geneticist at the VU University Medical Center in Amsterdam, the Netherlands, and her co-workers concluded that stem cells hold the key to understanding the limits of an individual's lifespan. Since uncovering the link between stress and telomeres3, Blackburn has taken up exercise and meditation, and at Lindau she encouraged me to do the same.
