Sorry, I don't get it. I am enjoying my encore career in academia, following a 35-year run in industry. I had tentatively planned to retire at age 70 (two years from this coming summer), but I may keep going beyond that. The saving grace is a much more flexible work schedule, including working from home most Tuesdays and Thursdays, and the fact that I now work "only" 40 hrs/wk., instead of 50 or 60.

The other saving grace is financial independence, and the knowledge that I now work at a job that I could afford to walk away from at any time.

One of my friends, who is 10 years my senior, retired from teaching electrical engineering for 50 years at San Diego State, and now he works part-time with me as an adjunct prof. at UCSD. His friends tell him he "sucks at retirement." Another role model is local oceanographer Walter Munk, 101, who says, "I work because I still can."
