(CNN) — The search for immortality is a tale as old as time, but it certainly has taken on a new look.
The ancient Mesopotamian epic “Gilgamesh” chronicles a king’s search for immortality after the loss of a friend. Myths of a “fountain of youth” prevailed from the times of Alexander the Great to the golden age of Spanish explorers in the 16th century.
Now, tech billionaires are using artificial intelligence, supplements and medical treatments in their attempt to crack the code on living –– if not forever –– as long as they can.
This search — and the truth behind what leads to a longer, healthier life — is the subject of a six-part CNN Original Series called “Kara Swisher Wants to Live Forever.” The show, premiering 9 a.m. ET/PT Saturday, asks just how far the human effort toward longevity should go, what is mere snake oil, and how access to better health can make its way to the general population.
Swisher’s main takeaways? A lot of the investment the “tech bros” are making in longevity miss the point, but there are real, meaningful ways to increase people’s lifespan –– and health span, or living as long as you can, as healthy as you can that you can get started on now by slowly but steadily making lifestyle changes.
Here’s what the billionaires are getting wrong about longevity, and what you can start getting right today.
The point of it all
Another classic story of the search for immortality comes from Greek mythology. Eos, the goddess of the dawn, fell in love with Tithonus, a prince of Troy, and she sought to give him eternal life. But she made a mistake and didn’t specify that he would remain forever young. So, he lived forever, but he kept aging and his health kept declining.
The story raises a key question in the longevity conversation, Swisher said. Why do you want to live forever, at what cost and what would you do with more time?
Xuan-Mai Nguyen, a health science researcher for the Million Veteran Program at the VA Boston Healthcare System, tells her patients that as much as they may want to focus on adding years, she also wants them to maximize the present day.
“If you’re living five to 10 years in addition, what are those things that you want to do? Try to kind of be mindful and be purposeful in terms of what you’re trying to accomplish,” she said.
Many of the cultural icons who are seeking the elixir of youth are missing an important point. Like it or not, they –– like everyone before and everyone after –– will die; and instead of focusing on increasing the number of years, the cultural focus may be better served on relationships, purpose and impact on others, Swisher said.
When thinking about your older years, consider the difference between lifespan and health span: the number of years you live compared with the number of years you spend healthy.
“Our lifespan is much longer than our health span,” Swisher said. “How can we bring those two together?”
People are tending to live longer, but a longer life often means an increased risk of chronic disease, which can mean more frailty and disability in later years, said Dr. John Batsis, a geriatrician and associate professor of medicine at the University of North Carolina at Chapel Hill.
“My experience is that living longer is less important than living a healthier, disability-free life,” he said in an email, referring to patients. “I take care of older adults, and many would rather have greater function rather than live longer with greater disability.”
