Longevity is everywhere right now. It's on supplement bottles, in podcast titles, in health apps and in conversations about the future of medicine. For some people it's exciting. For others it's another trend to be a little sceptical of.
Both reactions make sense. But underneath the buzzword is a question worth taking seriously: not just how to live longer, but how to live well.
Living longer isn't the same as living well
Life expectancy has risen around the world. Health hasn't kept up. A study across 183 countries found that people now spend, on average, almost ten years at the end of their lives in poor health.
That's why researchers and health experts increasingly talk about healthspan: the years we live in good health, not just the total number of years.
There's also a quieter problem with the longevity conversation. Tracking every number, chasing the perfect routine and worrying about ageing can easily become another source of stress. And chronic stress is one of the things that takes away from living well, both now and over time.
Most of us aren't fully here
If living well means being present for your own life, most of us have room to grow.
In a large study of 2,250 people, researchers found that people spent almost half their waking hours thinking about something other than what they were doing. Replaying the past, planning the future, somewhere else. And people were generally less happy when their minds wandered than when they were focused on the moment.
So a version of longevity that pulls our attention even further into the future may not be the answer.
How we live today shapes tomorrow
The good news is that the biggest influences on how long and how well we live are surprisingly ordinary.
Around 40% of early deaths are linked to everyday behaviour: how we move, eat, sleep, connect with others, and handle stress. Genetics and healthcare matter too, but a large share of our long-term health is built in daily habits.
In other words, the future version of you is being shaped on ordinary days, in small things repeated over time. That's not a reason to obsess over tomorrow. It's a reason to take today seriously.
Why everyday stress matters
Our bodies are built for hard moments. A deadline, a difficult conversation, a stressful week: the stress response is designed to rise, help us cope, and then settle again.
The problem is stress that never gets the chance to settle. When it builds up over months and years, it shows up in sleep, digestion, immune function, mood, relationships and heart health.
The other side of this is encouraging. Small, regular moments of rest can make a real difference. In one study, five minutes a day of slow breathing with longer exhales was enough to noticeably improve people's mood within a month.
Three small ways to live well today
Catch one moment when you're somewhere else. On your phone at dinner, replaying a conversation in the shower. No judgement. Just notice it, and bring your attention back to what's in front of you.
Let the exhale be longer than the inhale. Three slow breaths, a few times a day. Before you open the laptop, before you walk into the house, before you reply to a difficult message.
Do one thing that makes the day feel lived. A walk outside, a meal with someone without phones, a song you listen to all the way through.
None of these need much time. Their value comes from doing them often.
Something to notice
Where does your mind go most when you're not present: the past or the future? And what's one moment this week when you were completely there?
Baseline offers one to three minute resets for the moments a busy day pulls you away from yourself. Not to make you calm all the time, but to give you more capacity to be in your life, today. Try it free for a month.
