The world population is aging as life expectancies increase due to improvements in health, sanitation and lifestyle. This is fundamentally changing society as workforces become more age diverse and families have fewer children across more generations. However, cultures and social norms have not adapted to support longer lives. There is a need to strategically rethink how to utilize added decades of life through changes like increasing retirement ages and developing new models of flexible or part-time work for older individuals. Tapping into older populations' knowledge and skills could benefit societies and economies while also providing individuals with meaningful engagement and improved well-being.
