A Practical Take on Longevity for Advisors & Clients

Bradley JensonAdvisor Perspectives welcomes guest contributions. The views presented here do not necessarily represent those of Advisor Perspectives.

There are at least three distinct perspectives emerging from the scientific debate over human longevity:

  • Radical life extension
  • Longevity optimism
  • Longevity skepticism

Each offers a different way of thinking about how long we might live.

Radical life extension advocates believe science could eventually achieve “longevity escape velocity,” in which advances in geroscience and biotechnology extend healthy life faster than people age. Scientists such as Dr. David Sinclair of Harvard Medical School and Dr. Aubrey de Grey of the Longevity Escape Velocity Foundation have suggested that lifespans of 150 years or more may eventually be possible.

At the other end, longevity skeptics such as Dr. S. Jay Olshansky of the University of Illinois Chicago argue that the dramatic gains in average life expectancy achieved during the past century may be difficult to extend further. Much of that progress came from public-health advances such as sanitation, clean water, vaccination, antibiotics, and improved nutrition. However, longevity skeptics can still be optimistic about health span — the years we live in good health — even if substantial increases in maximum lifespan prove elusive.

Bridging the Chasm

But I want to focus on a middle position: longevity optimism.

Longevity optimists believe advances in geroscience, biotechnology, artificial intelligence, and other fields could significantly extend both health span and lifespan, without suggesting that people will live for 150 years or longer. From this perspective, living healthy into our late 90s, and perhaps beyond 100 for many, should be taken seriously when thinking about our personal and financial futures.
