The age beginning older adulthood is undergoing change. While many researchers continue to make 65 as the entry point, today there is no set age:
• The Older Worker Benefit Designation Act (1990) begins older adulthood at age 40.
• AARP invites those at 50 to join.
• Senior discounts vary from 50 on up.
• Senior centers may require entry for those 50+.
• 62 is required for partial Social Security.
• Medicare requires the recipient to be 65.
• Employers either have raised age limits or omitted them altogether.
