Mentoring and coaching are usually thought of as an older, more experienced person guiding a younger inexperienced person.
However, in a time of a great change, it may make sense for the senior person to have a junior coaching him or her as the young generally do better adapting to, or creating, change than those who have created and or nurtured the status quo.

Maybe those Boomers with a few years yet to go should consider doing likewise.
