We think of ageing as an inescapable fact of life – we’re born, we grow old, so it goes. “That’s been the narrative for thousands of years,” he says, on a video call. But what if it didn’t hav e to be?Steele began professional life as a physicist. As a child, he was fascinated by space, the way many scientists are. But he has spent the past three years researching a book about biogerontology, the scientific study of ageing, in which he argues the case for a future in which our lives go on and on. Steele considers ageing “the greatest humanitarian issue of our time”. When he describes growing old as “the biggest cause of suffering in the world,” he is being earnest. “Ageing is this inevitable, creeping thing that happens,” he says.
