心理學家 Laura Carstensen 是 Stanford Center on Longevity 的首任總監，她認爲由於現代先進國家人類的預期壽命以及健康情況都大幅提升，過去那種 25 歲左右開始全職工作、直到 65 歲退休的 “衝刺” 式工作形態應該相應的調整，轉變爲馬拉松長跑般、一種較低工作量、但延展到幾乎全部人生的職業生涯，如此對個人的心理健康會有不少幫助、整體社會的生產力也應能提升。
Carstensen 認爲，理想上我們應該延長學習的時間，從 40 歲才正式開始全職工作，在人生晚期漸漸轉變成兼職工作，直到 80 歲完全退休。
Full-time ideally would begin around the age of 40, rather than in our early 20s. Careers would be longer, with a gradual transition to part-time work in the later years before full retirement around age 80.
For many people, most of those years will be healthy enough to continue work that doesn’t involve intense physical labor. So why are we still packing all of our career and family obligations into a few frantic decades?
… But many of us already are making trade-offs under the old model, in industries that are not yet accustomed to accommodating parents or older workers who want to work part-time.
最困難的是如何改變現有社會的思維方式，但一旦轉變開始， Carstensen 樂觀地認爲，這個趨勢會成爲一股浪潮：
“There is no real reason why we need to work this way. The hardest thing is, how does [change] start?” Carstensen said. But “once it starts, there’s very little question that it’s going to roll on.”
