How old is your body, really?
Five lands, nine playful challenges, about ten minutes. Breathe, talk, listen, tap, balance and answer a few questions. Dr Fox turns it all into your biological age.
An estimate for fun and motivation, not a medical test.
Your assessment
Tap a land to begin. The glowing one is next.
Play as many as you like. Skipped challenges don't count.
Breath power
Why it matters: how long you can hold a steady "aaah" shows breath control and lung power, which fade with age and inactivity.
No microphone here? It works fully on londevity.com. For now, use the stopwatch: tap it, say "aaah", tap again when you run out.
Voice check
Why it matters: a strong, steady voice uses the same breathing and throat muscles that keep you talking, singing and swallowing well for life.
"Every morning I walk to the park, smile at the sun, and breathe in the fresh air."
The microphone is blocked in this preview. The voice check works fully on londevity.com. Skip it for now.
Voice fitness is a fun score. It isn't counted in your biological age and it can't diagnose anything.
Reaction speed
Why it matters: quick reactions help you catch a trip, a dropped cup or a car braking ahead.
Pattern memory
Why it matters: holding a pattern in mind is what lets you follow a recipe, directions or a conversation. Use it or lose it.
Hearing age
Why it matters: the highest sounds are the first to fade as ears age. Looking after your hearing keeps your brain busy and you socially connected.
Face age scan
Why it matters: sun, smoking, sleep and stress all show on the skin. How old you look is a fun mirror of your daily habits.
Flamingo balance
Why it matters: standing on one leg tests balance, strength and brain working together. Good balance helps prevent falls.
Safety first: stand next to a wall or sturdy chair you can grab. Skip this if you feel dizzy or have balance problems.
Chair stand
Why it matters: getting up from a chair quickly shows leg strength, one of the best signs you'll stay independent as you age.
Safety first: use a sturdy chair against a wall. Skip this if you have knee, hip or back pain, or balance problems.
