There is a new study indicating that without mandatory retirement, many more faculty are retiring in their 70s and into their 80s. Some faculty will continue much as they have before, but it seems that if the teaching loads are more modest, opportunities for external employment are absent, and salaries are not paramount, then faculty are less likely to retire.
Will we continue to do our research? Are our courses up to date, and reflect current controversies? Does our deep experience affect the classroom, the seminar, the faculty meeting, etc
How do you know when it is right for you?
