But it would almost certainly be illegal under equal protections. Once it's determined that 67 is safe, you cannot allow some folks (kids) to go to 67 but cap others at 65.083. Federal law cannot supersede equal protections (constitution).

Might be a work around, ie claim that for safety reasons you want to slow roll the age increase and monitor the results carefully over time. It would be challenged but might hold up OK.
