Deb Workman and Arnold Stalk are baby boomers, two of the 76 million Americans born in the post-World War II baby boom between 1946 and 1964. While their careers are very different, they answer the question — when are you going to retire? — the same way.

“Never.”

Workman, who stayed home raising her three children before becoming a nurse in her 40s, is a 54-year-old recovery room nurse at Spring Valley Hospital, a woman who paid her own way to the Philippines to help the 2013 victims of Typhoon Haiyan, a catastrophe that left more than 6,000 dead.

“I have a desire to help people that my mother instilled in me,” Workman said. “I enjoy golf and cruises but that gets boring if you want to contribute to making a better society.”

Stalk, a 61-year-old architect, designed emergency family shelters in California after undergraduate architectural study. He founded Veterans Village Las Vegas through a public-private partnership, converting the 125-room former Econo Lodge on the Strip into transitional housing for homeless veterans. The achievement drew the attention of first lady Michelle Obama, who honored him recently at the White House.

“Until my last breath, I’ll try and make life easier for people,” said Stalk, father of a teen and two grown children. “I feel my career is like the space shuttle before orbiting. I’ve only begun to do what I’m capable of doing.”

The nurse and architect are examples of a growing number of baby boomers who believe in what Minnesota author Chris Farrell calls “unretirement.” His book, “Unretirement: How Baby Boomers Are Changing the Way We Think About Work, Community, and the Good Life,” notes that boomers — expected to live longer in better health than any before — are often extending their working lives, frequently venturing into new careers, entrepreneurial ventures and volunteer service. A Gallup study found that one in 10 boomers predict they’ll never retire.

“Many boomers work for a sense of purpose,” Farrell said in a phone interview.

Though a Banker’s Life study shows money is the top singular reason for continuing to work for many employed retirees, six in 10 work for nonfinancial reasons, including to have a sense of purpose and to stay mentally alert.

Stalk has used a doctorate in architecture to help complete more than 50 housing projects for the disadvantaged in California and Nevada, always getting private donations of everything from food to furniture to leverage against tight public money. Las Vegas Mayor Carolyn Goodman called his ability “amazing” and U.S. Rep. Dina Titus, D-Nev., said he’s “remarkable.”

Nora Luna, a Nathan Adelson Hospice supervisor who’s worked with Stalk on projects, added: “He puts his own money where his mouth is.”

Stalk said, “My grandfather, who escaped the Warsaw (Poland) ghetto, drilled into me that I have to give back, ”

Workman, who’s studying to be a nurse practitioner so she can help people with their primary care, tears up as she recalls people she’s helped. Earlier this year, she and her husband came upon a horrible motorcycle accident as they drove home from Utah. When CPR didn’t help, Workman held the motorcyclist’s hand and talked to him until rescue vehicles arrived.

“I didn’t want him to die alone,” she said, sobbing.

Julie Bemb, the mother of Zach Kilgore, who died in the accident, saw a photo taken at the scene and found the woman pictured who tried to save her son.

“I had to thank her,” Bemb said. “She’s an angel.”
