Ageism or age discrimination is arguably the last widespread, identity-based form of discrimination still to be tackled on a global scale. It perpetuates and heightens inequality, it dehumanises, and it holds us all back. Our human rights should not weaken as we age. We all hope to grow old. The 21st century will be an era of hyper longevity, so let's all come together to make our ageing world a great world to live in.
