How longevity is changing our retirement outlook: Author Q&A

At the recent annual conference of the American Society on Aging, Ken Dychtwald, a psychologist and gerontologist, spoke about what has pushed him for roughly five decades: finding ways to successfully navigate longer life spans, which was the topic of his provocative keynote address, “The Longevity Revolution: Triumph or Tragedy?”

One of history’s greatest accomplishments — increasing longevity — could turn out to be one of the world’s biggest challenges, said Dychtwald, a bestselling author of 19 books including “Radical Curiosity: My Life on the Age Wave.”

I caught up with Dychtwald after his talk to learn more (edited excerpts):

Kerry Hannon: What’s the impact of longer lifespans for retirees today?

Ken Dychtwald: Let’s set the stage in terms of the grand phenomenon of longevity because most people are inclined to think, well, I'm living a little bit longer than my grandparents did.

What I like to remind people is that throughout 99% of human history, the average life expectancy worldwide was under 18. Sure, there were some 40- and 60- and 70-year-olds, but there were very few. Life was short, you know, brutish, as we've heard. And most people didn't contemplate the idea that there would be a retirement.

Then, in the early part of the 20th century, we had breakthroughs in penicillin, antibiotics, public health, and surgical procedures. People began to take better care of their own well-being.

More people are now expecting that they're going to live to 80 or 90 or even more years. In fact, the average life expectancy in America is now 78. But that's a little misleading because if you look at life expectancy at 65, it's about 20 more years. That's a lot of time.

So what does that mean in practical terms?

This impacts retirement in three ways. Gen Xers and boomers are thinking of retirement as a whole new chapter in life. Our parents and our grandparents were inclined to think of it as a wind-down. You had lived your life. You'd have a few years to socialize, collect your thoughts, watch some TV, take a nice trip or two, and then you'd expire.

People are envisioning the idea that post-work years are becoming longer and offering more possibilities than they ever did before.

The second thing is, a lot of people are scratching their heads and saying, ‘Yikes, I don't know if I can afford that 20 years of life.’ That's reasonable. Unless you're very wealthy, living another 20 years after your earning years, relying on government safety nets or relying on savings may not go the distance. People are terrified of the idea of becoming a burden on their family or running out of money.
