65 is only a "common retirement age" because it's the age you can receive many types of retirement benefits without penalty, and become eligible for Medicare in the United States. In other words, for many Americans, it's the first age at which they can afford to retire.
For someone like Cook, he could've retired at 50 if he wanted to. But 65 is just another year and doesn't have any more or less weight on a decision to retire like it would for working class folks. Nothing, financially, has 'changed' for him with that birthday.
I mean I know a lot of 'semi-retired' people personally who had fully vested pensions or who had reached retirement savings goals in their 50's, but work part-time somewhere just for health insurance.
