Frequently Asked Questions

Is "biological age" a real thing?
Yes. Biological age is measurable via several validated biomarkers: epigenetic clocks (Horvath 2013, GrimAge 2019, DunedinPACE 2022), telomere length, blood-test composites (Levine PhenoAge 2018, Klemera-Doubal). It's a research-grade construct showing how fast you're aging biologically vs the calendar. Two 50-year-olds can have bio ages of 42 and 60 based on lifestyle + genetics.
How accurate is THIS calculator?
This is a SIMPLIFIED lifestyle-based proxy. It captures roughly 60-70% of the directional signal of full biological-age tests. For ground-truth bio age, services like TruDiagnostic, Elysium Index, or similar offer epigenetic clock testing (~$200-400). This calculator is free + directional — useful for "is my lifestyle adding or subtracting years" decisions.
Can I really lower bio age?
Yes — research shows this is highly modifiable. Fraga 2005 twin studies: monozygotic twins drift apart epigenetically based on lifestyle. Belsky 2024: pace-of-aging slowed by 0.5-1 years/decade with: 7-9hr sleep + Mediterranean diet + 150 min exercise + no smoking + low alcohol + high social engagement. Bio age is the most leveraged longevity intervention.
What's the highest-impact change?
In rough order of effect-per-effort: (1) STOP SMOKING (biggest single shift, ~5-10 yrs of bio age). (2) Sleep 7-9 hrs consistently (cellular repair window). (3) Reduce alcohol (genotoxic). (4) Strength + zone-2 cardio 150 min/wk. (5) Mediterranean-style diet (high polyphenols, low ultra-processed). (6) Social engagement (loneliness ages cells). (7) Stress regulation (cortisol = aging accelerant).
