Author Q&A: The challenges of aging in America

Worried about getting old, outliving your money, or loneliness? You’ve got plenty of company.

By 2030, 1 in 5 Americans will be 65 or older, and by 2050, the US is projected to have nearly 1 million centenarians.

In her new book “The Second Fifty: Answers to the 7 Big Questions of Midlife and Beyond,” Debra Whitman, an economist and AARP’s executive vice president, explores challenges and opportunities we all face as we age. These run the gamut from longevity to brain health, finances and jobs to housing, and, importantly, the role that relationships and social engagement play as the decades roll out.

Here's what Whitman had to say about navigating life after 50 with grace, good health, and firm financial footing, edited for length and clarity:

Kerry Hannon: Why are you optimistic about the challenges of aging?

Debra Whitman: I'm optimistic because older people are our fastest-growing natural resource. If we treated them as such and leveraged the value of experience, we could be driving GDP growth and fueling our economy, as well as giving people a bigger sense of purpose.

We overlook the contributions older people make and overestimate the need for care.

Plus, having a mindset that aging is a positive thing can affect our economics, but it also affects our personal health and well-being. If you have a positive view on aging, you live 7 ? years longer than if you have a view that aging is a time of decline and despair.

You write that there are social reforms and medical reforms that can make a huge difference for people navigating the second half of life. Can you elaborate?

We need a national strategy on aging which encompasses everything from healthcare to financial security to making sure that long-term care works or transportation or housing systems are all integrated in looking at the needs of an aging society.

How is working as we get older good for us?

Working can be financially good for us. Many people need the money to supplement their Social Security checks or retirement savings. I was really surprised at how much of the gig workforce is people over age 50 — 20% of gig workers are 55-plus.

But working also can help us cognitively. If you have a stimulating job — one that challenges your brain — that can keep you healthier for longer. When we look at people who retire and don't have regular exercise or social interactions, just six years of retirement can raise their risk for illness and disability and affect cognitive function.

It could be through volunteer work, not paid work, but maintaining an active mind is really important as we age.
