Live to 100 projects your lifespan from official life tables and your real habits, then shows exactly which levers add years and which ones are quietly costing you.
No account, no email, no sign-up. One click and everything runs right here in your browser.
Your plan updates daily based on your goals and the latest longevity signals.
Based on population-level life tables for your age, sex, and country.
Source: CDC/NCHS 2021Adjusted for your reported habits, goals, and trajectory inputs.
Population-based statistical estimate. Not an individual medical prediction. See sources below.
Current estimate 91.6 years. This model is directional, so Live to 100 shows a range instead of pretending to know the exact day.
Your estimate is only half the picture. This shows how much distance is left to age 100, and which levers actually close that gap.
The model says you are 8.4 years short of age 100 on the current path.
We start with official life tables, then layer simplified adjustments from your habits, momentum, and scenario sliders so you can see what is actually moving the number.
Live to 100 scores how grounded the projection is, based on objective markers, recent check-ins, and how much history this browser has already collected.
Live to 100 compares realistic next-step upgrades and ranks the ones that appear to buy the most upside from this exact profile.
Live to 100 breaks the current estimate into the specific factors it is using, so the number feels auditable instead of mystical.
Live to 100 tracks how current each evidence layer is, so older labs or stale check-ins do not quietly feel as solid as fresh data.
Add a few optional biomarkers so the projection can respond to something more concrete than habits alone.
Add a few common wearable metrics so readiness, aerobic fitness, and sleep consistency can influence the plan.
Add the therapies or support layers you are already using, so the plan does not treat you like a blank slate.
This is the feedback loop that keeps the model responsive. Log the behaviors, then watch your trajectory and projected lifespan update.
Live to 100 snapshots your current estimate each day so the product can show trend, not just a single number.
Once this browser has more than one saved day, Live to 100 will explain what changed instead of just showing a new number.
Live to 100 turns your current trajectory, biomarkers, and momentum into a concise doctor-ready summary with specific questions to ask.
Live to 100 turns your current snapshot into a simple measurement cadence, so you know what to check now, what to re-test next, and what would count as a real win.
Live to 100 turns the current profile, behavior streak, biomarkers, wearables, and trend history into a simple operating board you can actually manage.
Live to 100 turns the current snapshot into a practical decision board, so the next move is clearer than just reading a stack of cards.
Live to 100 turns the current trajectory into a practical seven-day operating plan, so the product does not stop at explanation.
Live to 100 packages the current estimate, operating priorities, and science watchlist into one concise weekly brief you can actually use.
Live to 100 turns the raw feed into a practical alert board, so you can separate immediate action from interesting noise.
These scenarios show where the model sees the clearest upside if the changes actually stick.
This makes the estimate feel responsive instead of static. Push consistency and recovery up, and the projected lifespan, hourglass, and Sankey all update immediately.
Your biological age estimate gets pulled lower when your daily inputs trend in the right direction.
Get fast, source-aware answers about your current trajectory, what moved the number, and what deserves attention this week.
