From a Wall Street Journal story by Julie Halpert headlined “A Former ER Doctor Finds New Ways to Use Her Medical Skills in Retirement”:

As an emergency-room physician, Paula Glosserman didn’t have time for much else for many years.

“I loved my job and never doubted that I made the right decision,” she says.

Even so, she grew weary of working overnight, weekend and holiday shifts.

She decided to take full early retirement at 58. It allowed her a pension while she continued to work at a reduced schedule for the next seven years.
