🎙️ How Old Is Too Old to Lead? Life Lessons from Aging Leaders, Brain Science, Blue Zones & Tardigrades


By Ephraim Agbo 

Cameroon’s President, Paul Biya, aged 92, has declared his intention to run for an eighth seven‑year term—potentially extending his rule until age 99. Biya has held power for 43 years, meaning that over 75% of Cameroonians have never experienced a different leader. Biya currently holds the title of the world’s oldest sitting head of state, and shows no sign of stepping down.

This scenario resonates far beyond politics—it prompts reflection on longevity, leadership, and the passage of time in mind and body.


🧠 Slower, Not Weaker: What Brain Studies Reveal

Although memory lapses and word-finding moments often come with aging, cognitive science suggests a different story: a 2022 global study of 1.2 million individuals aged 10 to 80 found that while reaction times decline gradually after age 20, mental sharpness remains robust until about age 60. Delays in response were attributed to increased decision caution, not cognitive decline.

In essence: slower responses may reflect growing thoughtfulness—not diminished capacity.


🌍 Questioning “Blue Zone” Longevity

Blue Zones—such as Sardinia (Italy) and Okinawa (Japan)—are celebrated for remarkable rates of centenarians who supposedly thrive thanks to diet, community, and purpose. Yet, researcher Dr. Saul Newman challenges this narrative. The Ig Nobel–winner, in his study of supercentenarian, found that 80% lacked birth certificates, and that government audits in Japan revealed 82% of those registered as over 100 had already died, sometimes decades previously.

One striking example involved a woman hiding her deceased father’s body for 30 years to fraudulently collect his pension. Such findings suggest that administrative gaps and poverty, rather than lifestyle, may explain longevity statistics.


🐻 Nature’s Rewind Button: The Tardigrade

Enter the tardigrade, also known as the water bear: a microscopic creature capable of surviving extreme conditions—heat, freezing cold, intense radiation, even outer space. When desiccated, tardigrades enter a state of suspended animation that can last decades.

Once rehydrated, they resume normal life—aging only starts back up where it left off. Under ideal lab conditions, a suspended tardigrade may remain viable for tens of years beyond its typical two-month lifespan. Professor Thomas Boothby’s research explores whether tardigrade proteins could help stabilize vaccines, potentially transforming global healthcare logistics.


⚖️ Reframing Aging and Power

So what links these stories?

  • Paul Biya’s extended rule exemplifies how longevity in leadership can suppress democratic change.
  • Brain science indicates that cognitive aging often reflects caution, not decline.
  • Blue Zone myths appear more tied to record-keeping failures than health miracles.
  • And tardigrades demonstrate a literal ability to pause and resume life—challenging assumptions about aging.

💡 The Takeaway: Wisdom Over Years

Long life doesn’t guarantee value. Flawed records don't prove longevity. Mental alertness endures beyond age 60 for many. And surviving hardship may be more important than living forever.

Thriving with purpose, community, and honesty about aging may be more meaningful than chasing uncertain longevity myths. Even if global leaders stay in power into their 90s, it doesn’t change the fact that cognition, dignity, and authenticity define how well human life is lived.
