According to Fortune, an aging population is already creating economic challenges in the United States and other countries.
At the same time, more people are being diagnosed with conditions such as dementia and Alzheimer's disease, placing a significant financial burden on society.
According to the University of Southern California, these diseases cost approximately $781 billion in 2025.

More people are retiring early
Many Americans choose to retire before the age of 65.
According to a 2025 analysis published in The Scandinavian Journal of Work, Environment & Health, a large proportion of the long-term unemployed are over the age of 55. At the same time, the average retirement age for men has declined over recent decades.
Fortune also reports that early retirement may result in lower retirement benefits, as many people choose to begin receiving Social Security benefits earlier than they are eligible to do so.
