I'm a level 7 individual contributor in tech in my early fifties. With four kids soon all in college and a late start (last year) on active retirement investment, I plan to work till age 65. I actually enjoy my work and my team at Fidelity.
Assuming I wont' be laid off, is it a realistic expectation to work till that age, as an individual contributor or should I transition into one of those "leadership" roles to stay on longer?
