New Book Argues Aging Isn’t One-Way: The “Flicker Stage” Suggests You Can Move Back to Youthful Function

Authors Stuart Kaplan and Marcus Riley, in Your Aging Advantage, present the “flicker stage” concept: functional age can temporarily reverse through deliberate lifestyle and mindset shifts, urging people to “age on pace” rather than accept inevitable decline.

  • Flicker stage: vitality can move up and down, not only decline.
  • Triggers matter: physical, social and psychological changes can flip someone to a younger-feeling state.
  • Policy and local impact: “aging on pace” may reshape work, training and community programs, especially in places like Hesperia, CA.

What the authors say about the flicker stage of aging

Stuart Kaplan and Marcus Riley frame aging in Your Aging Advantage as a fluid, seven-stage process that includes a flicker stage — periods when people feel significantly younger, then return to their chronological-feeling age. The authors emphasize these shifts are not fixed and can be influenced by deliberate action.

  • Flicker triggers: Riley highlights physical, psychological, social and environmental changes that flip someone back to a younger-feeling state — e.g., a new exercise plan, renewed social ties, or a refreshed attitude toward work or hobbies.
  • Kaplan’s analogy: your birth certificate gives a number, but your feels-like age is a lived experience shaped by humidity-like factors such as stress or health; think of it like a weather report rather than a fixed forecast.
  • Aging on pace: they urge readers to choose how to spend later years rather than accept 65 as a culturally imposed decline point.

How this idea differs from common views

The book challenges the widespread belief that aging is a steady, irreversible march. Instead, Kaplan and Riley argue people can move up and down stages of vitality, and they push back on age 65 as a societal, not purely biological, benchmark.

Where the idea sits with scientific research

The flicker stage is presented as a behavioral and psychological model, distinct from laboratory efforts to reverse cellular aging. Still, both lines of thinking share the notion that aspects of aging may be modifiable.

Examples of related scientific work include:

Important: the laboratory findings speak to cellular markers and early-stage therapies; they do not validate the book’s seven-stage population model or prove that behavioral flickers equate to cellular rejuvenation.

Transparency and limits of verification

A note on sourcing: independent searches did not find wide external references to Stuart Kaplan, Marcus Riley, or the book Your Aging Advantage and its seven-stage model. The description here is based on material supplied to Times Media Service. Readers should view the model as a new idea that has not yet been broadly peer-reviewed or widely reported.

Practical steps the authors promote

Kaplan and Riley ask readers to identify personal flicker triggers. Common examples include:

  • Regular exercise or a new fitness routine
  • Renewed social connection with family, friends, or community groups
  • Mental challenges such as learning new skills or returning to work
  • Environmental changes like moving to a more active neighborhood or volunteering

Their message is action-oriented: setbacks or stress can make you feel older, but positive moves can flip you toward feeling younger. The emphasis on personal choice aligns with values of self-reliance and personal responsibility.

What this might mean for Hesperia, California

Economic impact: As part of the Victor Valley economy, keeping experienced workers engaged could benefit local businesses and public services. If residents adopt flicker-stage strategies and choose to work longer or in flexible roles, Hesperia might see reduced retirement funding pressure and sustained consumer spending.

Political consequences: Reframing 65 as a flexible benchmark could influence local debates on benefits and city hiring. Conservative voters who emphasize self-reliance may support policies that enable longer workforce participation and retraining.

Social effects: Hesperia’s senior centers, churches, and volunteer groups could amplify flicker triggers — social connection and purposeful activity — boosting volunteerism and civic engagement.

Cultural relevance: The High Desert’s independent, hard-working culture may respond well to messaging that highlights personal choices — fitness, work, faith and family — as tools to manage aging on one’s terms.

Practical applications: Local health providers, gyms and senior organizations could adopt low-cost programs based on the book’s triggers: group exercise, skill classes, and employer-driven part-time roles that fit “aging on pace” goals.

Questions residents should ask

  • Is this model backed by research that applies to people, not just cells or small studies?
  • What local resources exist to help someone identify and use their own flicker triggers?
  • Can employers in Hesperia offer flexible roles, retraining, or volunteer pathways to help residents age on pace?
  • How can families and faith communities support members who want to remain active and engaged?

Sources and further reading

Reporting note

The flicker-stage description and seven-stage model come from Stuart Kaplan and Marcus Riley and materials supplied with the book Your Aging Advantage. Independent searches did not find wide external coverage of the book at the time of reporting. The biological research cited represents separate scientific efforts exploring reversible aging concepts and does not validate the book’s stage model as proven fact.

“Think in terms of aging on pace — choose how you want to spend your later years,” the authors urge, framing aging as a domain for personal choice and action.
