Here’s something you wouldn’t normally thing Bloomberg would be promoting:

It’s just too grueling. We have to take breaks,” says Lynda Gratton, a London Business School professor and co-author of The 100-Year Life: Living and Working in an Age of Longevity. “Why wouldn’t you want to take some of the retirement at the end of your life and distribute it to the middle of your life?”

The sabbatical—a chance to recharge midcareer—is hardly a new idea, and it’s still common in academia. But until recently most wouldn’t dream of quitting their jobs just to have fun for a year or two. And, as Gratton acknowledges, doing so is still a financial impossibility for the vast majority of workers.

For well-paid workers in high-demand fields such as technology, however, the idea may be catching on.
