– Chauncey Incarnato cycled through a variety of jobs after graduating from college: construction, personal trainer, hotel bellman, bouncer at bars. But none stuck, and even long workweeks barely covered his bills.

Incarnato was skeptical when his mom, a nurse for more than 30 years, suggested a career in health care. But after a six-month course to become a certified nursing assistant, Incarnato discovered caregiving instincts he didn't realize he had.

Working at a skilled nursing facility, Incarnato found the physicality of the job, plus the relationships he formed with patients, deeply rewarding. He went back to school to become a registered nurse and hopes more men follow suit.

"Once you're the person in the room talking to the patient, seeing the ramifications of the choices you make, I don't see how anyone cannot be pulled into it," said Incarnato, 31, now a nurse in the neurological trauma intensive care unit at Northwestern Memorial Hospital in Chicago.

Incarnato is part of a small but growing contingent of men pursuing jobs traditionally dominated by women in the fast-growing health sector, a choice some economists say may be key to stanching a troubling exodus of men from working life.

The rate of U.S. men participating in the labor force, meaning they're working or looking for work, has been declining for 50 years, a trend that could carry ramifications for economic growth as well as individual and family well-being. And more automation, particularly advancements in artificial intelligence, threatens to disproportionately hit traditionally male-dominated jobs going forward.

Meanwhile, nine of the 12 fastest-growing jobs in the U.S. are in health care, topped by occupational therapy assistants, physical therapy assistants and nurse practitioners, all positions that are held mostly by women.

"The growing professions are more caring," said Nicholas Eberstadt, a political economist at the American Enterprise Institute and author of "Men Without Work," which was published last year. "Can this be a man's world too?"

Some say it needs to be, not just for the sake of men, but for the sake of the health care field. Take nursing, which will need an estimated 1.13 million new registered nurses over the next decade, half of them to replace retirements, according to the American Nurses Association.

Efforts to bring more men into the nursing ranks seem to be working, albeit modestly. About 10 to 12 percent of registered nurses are men, compared with less than 3 percent in the early 1970s, according to census figures.

It could also bode well for men's future employment prospects, given projections that the jobs that will survive advancements in artificial intelligence are those that require distinctly human capabilities, like empathy, said Kristin Sharp, executive director of the Shift Commission on Work, Workers and Technology, an initiative of public policy think tank New America and Bloomberg.

Under one scenario outlined by Shift, technological innovation over the long run could mean jobs will increasingly revolve around caring for others, including in fields such as elder care, child care, teaching and coaching. Keeping men engaged in the workplace will mean finding ways to interest them — and help them thrive — in these jobs.

Most disconcerting is the decline in work among men of prime working age, 25 to 54, when they should be most productive. The drop has been particularly acute among men with a high school degree or less, according to a paper issued last year by the White House.

It's not that these men are staying home with the kids; just 2 to 3 percent of men say they don't work because they are taking care of family, compared with 30 to 40 percent of women who say so, Eberstadt said. Nonworking men report spending less time taking care of family members than employed women.

Part of the reason less-educated men are opting out of work is that offshoring, globalization and automation have squeezed the manufacturing jobs that used to be their bread and butter, leaving them with fewer options. Depressed wages at the bottom of the ladder also provide little incentive to work, the White House paper said.

But many advanced economies have faced globalization and automation pressures without as severe a decline in working men, so the labor market likely isn't the only culprit, Eberstadt said.

The difficulty people with criminal records have trying to land employment, and drug addiction, particularly the opioid epidemic, also could be sidelining people from work, Eberstadt said.

Other research explores whether high-tech video games could be distracting young men, especially those with less education and more limited wage prospects, from leaving their couches and seeking jobs.

Juan Soto, 33, sees some of the listlessness among his peers and wishes they would be more open-minded to jobs in health care, as he was. The problem, he thinks, is that they take any job available for a paycheck and when they don't like it they give up.

"They have stopped looking for a passion," said Soto, of Chicago. "They stay home, they work in the streets."

Soto, who has his GED, worked in construction and did some warehouse work before he decided to become a certified nursing assistant. In April he graduated from a program at Advocate Health Care, funded by JPMorgan Chase, that trains underemployed people in historically disenfranchised neighborhoods in high-demand health care jobs. They are guaranteed an interview with Advocate and job placement assistance at the end.

Soto, the only man in his class of 23, hopes to set an example for his two kids, 10 and 13, both of whom want to be neurosurgeons.

"The first day we had orientation," he said, "I knew that's the place I wanted to be."
