As lifespans increase, it's projected that 2.1 billion people will be aged 65 and above by 2050.

Dr Reuben Ng is an Assistant Professor at the Lee Kuan Yew School of Public Policy, and a behavioural scientist who also spent 16 years in government consulting and research. He's an expert in ageism, social gerontology, and quantitative social science. It's in that context that we spoke to him about the ongoing longevity revolution and how our AI and agency are helping to reframe ageing in a positive light.
