Merete Rønn Lasnier

Founder · Health strategist

I help turn complex health information into clear next steps for real life.

I built Your Longevity because I kept seeing the same pattern: people over 40 who were already spending time and money on their health, but still did not know what to do next. That is what we are here to change.

 

Rikke Hein-Rasmussen

Co-founder · Medical doctor

I want prevention to feel medically grounded, practical, and easier to act on.

Rikke brings deep clinical experience to every plan. Her role is to make sure the guidance is medically sound and clear about what belongs to a doctor and what belongs to daily life.

Our mission

We help people over 40 stop guessing and build habits that hold in real life.

The 4-week body signals reset. Start here.

If you are not ready for a full programme yet, but want a clearer first step, this is where to start.

Who this is for
For people over 40 who want to start small, without tests, without pressure, and without committing to more than four weeks.

What you get

  • Daily tasks and check-ins in the app
  • Weekly reflections
  • Small strength habit
  • 2-minute calming pause
  • One body signals review call with a coach at the end

What happens first
You start by noticing. Not changing everything. Just paying attention to sleep, energy, stress, movement, and mood through simple daily tasks in the app.

  • No epigenetic test.
  • No extreme protocol.
  • No daily coaching pressure.

Why this matters
Most people over 40 do not need more to do. They need one calm place to start noticing what their body is already showing them. Four weeks. Simple tasks. One call at the end.
