New book argues aging can “flicker” — a temporary, reversible shift in how old we feel
A new book argues aging isn’t a fixed decline but a fluid experience: Kaplan and Riley introduce a “flicker stage” where targeted lifestyle, social, and mindset changes can temporarily make people feel significantly younger before returning to their chronological age.
- Flicker stage: Functional age can temporarily drop or rise based on daily choices and events.
- Flicker triggers: Physical, psychological, social, or environmental changes can produce reversible shifts in how old we feel.
- Contrast with biotech: This is a behavioral model distinct from experimental cellular or genetic rejuvenation efforts.
- Policy and social implications: If people sustain lower lived age, workforce, retirement, and community dynamics could change.
Key information
Book: Your Aging Advantage by Stuart Kaplan and Marcus Riley. Source material is based on an authors’ interview and public segment (Fox News video segment with Stuart Kaplan and Marcus Riley).
Main idea: Aging may not be a steady, one-way decline. The authors describe a “flicker stage of aging” in which people can feel significantly younger for periods, then return to feeling their chronological age.
Mechanism: The authors say flicker triggers — physical, psychological, social, or environmental changes — can shift a person’s lived or feels-like age.
Wider context: The lifestyle approach differs from scientific efforts aimed at cellular or genetic rejuvenation, such as research linked to Harvard scientist David Sinclair. For comparison, see NAD coverage on FDA clearance for Life Biosciences human trial and a related overview at the World Government Summit media hub.
What the authors mean by “flicker stage”
Kaplan and Riley describe the flicker stage as one of seven stages in their framework. They say it is a period when people feel younger in function and spirit for a time, followed by a return to feeling older. The authors compare feels-like age to a weather report: the thermometer might read 85 degrees, but humidity can make it feel like 95. Similarly, your lived age can differ from the age on your birth certificate.
The flicker stage suggests functional age is not fixed. Factors such as improved fitness, renewed social ties, or shifts in mindset can produce a temporary drop in lived age. Conversely, stress or setbacks can push someone to feel older. The key claim: these changes are reversible and people can purposefully “flicker back” to a younger-feeling stage.
How flicker triggers work
Riley explains that flicker triggers are specific actions or events that reset one’s pace. Examples the authors provide include:
- Physical triggers: starting or renewing an exercise routine, improving sleep, or addressing nutrition.
- Psychological triggers: adopting a growth mindset, setting new personal goals, or engaging in learning.
- Social triggers: rebuilding friendships, joining groups, or finding meaningful community roles.
- Environmental triggers: changing daily routines, travel, or modifying one’s living space to be more active-friendly.
“Identifying personal flicker triggers is central to using the flicker stage as a tool for healthier aging,” the authors say.
They argue these triggers allow people to intentionally shift their lived age through everyday choices.
Aging on pace, not aging in place
Kaplan and Riley push back on the idea that aging is about location or hitting a set retirement age. They coin “aging on pace” to mean choosing how fast or slow one wants to move through life stages. They argue the common focus on age 65 as a marker of decline is a social benchmark tied to retirement policy, not a biological inevitability. The authors encourage people to decide whether they want to keep working, change careers, or pursue new interests — choices that can affect lived age.
How this idea sits with scientific research
The flicker stage and the broader Your Aging Advantage approach center on lifestyle, mindset, and social connection — a psychological and behavioral model rather than a claim about reversing cellular aging.
At the same time, scientific research into biological aging is advancing. Some biotech efforts aim to change aging at the cellular or genetic level. For example, researchers linked to Harvard’s David Sinclair are exploring epigenetic reprogramming to restore youthful function to cells. Recent reporting notes that Life Biosciences received FDA clearance for a human study tied to this line of research, and overviews of the science appear in coverage such as the World Government Summit report.
The key difference is scale: Kaplan and Riley focus on functional reversals people can produce now through daily choices. Biotech approaches seek deeper, cellular-level changes that are still experimental. Both strands contribute to a growing discussion about whether aging must be treated as a fixed decline or viewed as a set of processes that can be altered.
What’s missing or unclear
Publicly available coverage of Your Aging Advantage — primarily the Fox News segment — provides limited detail about the full seven-stage framework and offers few concrete study results. The authors’ claims are framed as practical advice, not as findings from randomized clinical trials. Readers should note that evidence for short-term changes in lived age is largely anecdotal in the available coverage, while biological interventions are subject to laboratory and clinical testing before broader validation.
Practical steps the authors recommend
Kaplan and Riley encourage readers to:
- Identify personal flicker triggers and track when they feel younger or older.
- Prioritize physical activity, sleep, and nutrition that support energy and function.
- Reconnect socially through community, volunteer work, or sustained friendships.
- Reassess life goals and work choices to align with what makes one feel vital.
These are low-tech steps aligned with longstanding public health advice.
Implications for United States
Economic impact: If people maintain a lower lived age through lifestyle changes, more Americans might choose to work longer or return to the workforce, affecting labor force participation, tax revenues, and retirement program solvency. Employers may see benefits from a more active older workforce but may also need to invest in workplace health programs and flexible schedules.
Political consequences: The book’s critique of treating age 65 as a biological threshold challenges a long-standing policy norm. If public sentiment shifts toward “aging on pace,” policymakers could face pressure to revisit retirement age policies, Social Security planning, and workforce training focused on older adults.
Social effects: Emphasizing social connection and purposeful activity could reshape community programs. Local groups, churches, and civic organizations might see increased demand for volunteer roles and intergenerational programs that support lived wellbeing.
Cultural relevance: The “flicker stage of aging” reframes aging from a decline narrative to a series of states people can influence, supporting a cultural shift toward valuing experience and continued contribution.
Practical applications for everyday life
The book’s suggestions — exercise, social ties, mindset shifts — are low-cost, accessible interventions. Public health campaigns could nudge people toward these behaviors, possibly reducing healthcare costs over time if healthier living lowers chronic disease burden.

Reporting notes
Coverage of Your Aging Advantage is currently based on public interviews and promotional material from the authors. The framework offers practical advice and a new vocabulary for thinking about age, but detailed evidence on the seven stages and long-term outcomes was not available in the cited sources. Readers interested in the scientific developments should follow results from clinical trials and peer-reviewed studies for verification of biological claims.
