New book argues aging can “flicker” — feel younger or older depending on lifestyle, mindset and interventions
United States (Sonoma Times) – A groundbreaking new book, ‘Your Aging Advantage’ by Stuart Kaplan and Marcus Riley, introduces the ‘flicker stage’ — a concept that functional age can fluctuate by lifestyle, mindset, and interventions, enabling temporary reversals to younger vitality.
Key takeaways
- The book outlines seven stages of aging and names a newly described “flicker stage” in which people may feel younger or older over short periods.
- Feels-like age (lived experience) can differ from chronological age and may be intentionally shifted by identifying personal flicker triggers.
- The authors reframe aging from “aging in place” to “aging on pace”, emphasizing choice about work, activity and life goals rather than a fixed cutoff at 65.
- Behavioral and social interventions support short-term functional improvements; biological age-reversal remains an active but largely preclinical research area.
Overview
In Your Aging Advantage, authors Stuart Kaplan and Marcus Riley describe seven stages of aging and highlight a newly named “flicker stage” in which people may feel younger or older over short periods. The concept challenges the conventional view of aging as a steady, one-way decline and suggests functional age can move up or down in response to lifestyle, mindset and targeted interventions.
What the authors say about the flicker stage
Kaplan and Riley argue aging is not a single, straight line: instead, functional age can fluctuate. In their interview they emphasize healthy aging involves intentionally “flickering back” to a younger state after stress or setbacks make people feel older.
Riley urged readers to identify personal “flicker triggers” — physical, psychological, social or environmental shifts that help reset a person’s pace.
Kaplan likened feels-like age to a weather report: just as humidity can make 85°F feel like 95°F, our lived age can differ from the birth-certificate number. The authors say many people already live with that mismatch and can intentionally move into younger-feeling stages.
How the flicker idea fits with scientific research
The flicker stage is presented primarily as a conceptual, lifestyle-focused idea. Research shows behavioral and social interventions — exercise, social ties, mental health care and environmental changes — reliably affect strength, cognition and mood. These findings support the book’s behavioral notion of temporary functional improvements.
By contrast, laboratory research into biological age-reversal is active but mixed and largely preclinical. For instance, vision research measuring critical flicker fusion frequency (CFF) found a largely linear decline with age, suggesting some neural changes follow steady patterns rather than sudden reversals.

At the cutting edge, scientists like David Sinclair report experiments that partially reset cellular age in animals via temporary activation of embryonic genes and predict potential age-reversing treatments decades out. Those findings are promising but remain preclinical and require human trials.

Investigative perspective on evidence
The book’s flicker-stage operates at the level of behavior, psychology and social life. That kind of reversibility — feeling and functioning better after adopting new routines, improving social connections, or receiving care — is well supported by public health research.
However, claims about biological reversing of age markers are not yet established in humans. Media reports and optimistic timelines often highlight promising animal results but should not be read as evidence that humans can currently be made biologically younger in the lab. The book’s flicker concept sits comfortably within proven lifestyle impacts, while cellular reprogramming and epigenetic-reset science remain emergent and require clinical validation.
Practical “flicker triggers” and steps the authors suggest
- Physical: Regular exercise, strength training and mobility work to improve balance, endurance and strength.
- Social: Renew friendships, join groups, volunteer or reconnect with family to restore energy and purpose.
- Psychological: Therapy, stress reduction, and new learning to boost mental flexibility and resilience.
- Environmental: Changes to daily routines, living spaces, or travel that refresh outlook and energy.
The authors frame these actions as ways to “age on pace” — choosing whether to continue working, change careers, pursue new interests, or slow down when it aligns with personal goals.
Limits of current public reporting on the book
Coverage to date has highlighted the flicker-stage idea but has not published the full details of all seven stages described in the book. Readers seeking the complete framework should consult the book itself for full context.
Implications for Sonoma, California
Economic impact
Sonoma County’s economy includes small businesses, vineyards, hospitality jobs and many older residents. If more people adopt an “aging on pace” mindset, employers may see shifts in workforce participation — more people working longer, moving to part-time roles, or starting new businesses. Programs for retraining, flexible schedules and age-friendly workplaces could benefit employers and older workers alike.
Political consequences
Local policymakers may face pressure to expand services that help residents stay active and connected, such as community centers, transit for older adults, and incentives for hiring older workers. Reframing age 65 as a social benchmark rather than a biological limit could prompt discussions about phased retirement and supports for older workers.
Social effects
Sonoma communities with strong volunteer networks, arts programs and outdoor recreation are well positioned for flicker triggers. Expanding social programs, group fitness, adult education and intergenerational projects could help residents flicker toward younger-feeling stages and improve community health.
Cultural relevance
Sonoma’s culture values outdoor life, food and wine, and local community — assets that support flicker triggers such as walking trails, farmers markets and festivals. Messaging that frames healthy aging as personal choice and community engagement may resonate locally.
Practical applications for local organizations and residents
Health clinics, senior centers and nonprofits can incorporate the flicker-stage idea into outreach by promoting exercise groups, social meetups, mental health resources and learning classes. Employers in tourism, wineries and retail can pilot flexible schedules and training for older workers. Individuals can test inexpensive small changes — a new class, a volunteer role, or a walking group — as ways to try “flickering” back to a younger-feeling state.
