COVID-19 has highlighted the particular vulnerability of the aged. However, as we find out more about the ageing process, we are uncovering new ways to treat it. One revolutionary approach is to look at ageing as a disease and tackle its causes. With breakthroughs in genetics and emerging technologies, scientists have been able to make animals live longer. If this works on humans as well, will we hold the keys to postponing ageing and keep major diseases like Alzheimer's and cancer at bay?

David A. Sinclair, Ph.D. is one of the world's most famous scientists and entrepreneurs, best known for understanding why we age and how to reverse it. He is a New York Times bestselling author and a tenured Professor of Genetics, Blavatnik Institute, Harvard Medical School, co-Director of the Paul F. Glenn Center for the Biology of Aging Research at Harvard, Professor and Head of the Aging Labs at UNSW, Sydney, and an honorary Professor at the University of Sydney.
