Not Forever Young, but Better Old

A lot of people read that as proof the whole longevity thing is nonsense. I read it the other way around. Franz does not disprove longevity. He is one of the best pieces of evidence for it you could ask for. Just for the part almost everyone ignores.

Isn't Franz Doing Everything Right Without Even Trying?

Yes, pretty much. Franz has no gadgets and no pills. He has something else: people, a reason to get up, and a relaxed attitude toward his own age. And that belongs to the strongest stuff longevity research has ever found.

His life was no wellness program. Five years as a prisoner of war, and he came home an invalid. He never trained. He kept moving anyway: walked a lot, did his own small gymnastics. He never overdid anything, not food, not drink. He always knew where his red line was, he says. And one thing runs through all of it: his trumpet. Music saved his life, in his words. Movement, moderation, and something that matters to you. It sounds unspectacular. It is also pretty much what counts.

Start with relationships. A big review of 148 studies with more than 308,000 people found that strong social ties come with roughly 50% higher odds of surviving the study period (Holt-Lunstad, Smith, and Layton, 2010). That is about the same size as not smoking. So a 102-year-old who falls in love is not doing something cute. He is doing something that carries real weight in the data.

Then purpose. In a US cohort of nearly 7,000 people over 50, those with the lowest sense of purpose had almost 2.5 times the death risk of those with the highest (Alimujiang and colleagues, 2019). A separate study of more than 6,000 adults found that each step up in purpose lowered death risk by about 15%, at any age (Hill and Turiano, 2014). Pooled across ten studies and over 136,000 people, the same conclusion holds (Cohen, Bavishi, and Rozanski, 2016). People who have a reason to leave the bed in the morning live longer on average. For Franz, that reason is currently Doris.

The flip side is just as clear. A review of 70 studies covering 3.4 million people found that social isolation raises death risk by about 29%, loneliness by 26%, and living alone by 32% (Holt-Lunstad and colleagues, 2015). The interesting part: whether you are objectively isolated or just feel lonely barely changes the numbers. The feeling alone is enough to do harm.

That leaves your attitude toward aging. In the documentary, psychologist Eva-Marie Kessler says that thinking negatively about age turns into a kind of self-fulfilling prophecy. There is real research behind that. A much-cited Yale study found that people with a positive view of their own aging lived 7.5 years longer on average (Levy and colleagues, 2002). You have to stay honest, though. A newer pooled analysis of 107 studies confirms an effect, but a clearly smaller one (Westerhof and colleagues, 2023). The direction holds. I would not carve that exact number into stone today.

Stress gets physical. Chronic stress probably speeds up biological aging. In one small study, highly stressed women had shorter telomeres, the protective caps on the ends of your chromosomes that shrink as you age (Epel and colleagues, 2004). The gap looked like roughly a decade of extra aging. Careful, though: the study is tiny, only 58 women, and it proves no cause. As a hint at a mechanism, it works well. Larger reviews of over 120,000 people at least confirm that short telomeres track with higher death risk (Wang and colleagues, 2018).

Franz lives all of this without knowing a single study. That is his version of longevity. The shame is that almost nobody talks about it, because it does not sell.

So Is It Enough to Just Relax and Be Happy?

No. And that is the most important sentence in this whole piece. Franz is the exception, not the rule.

There is also the 100-year-old chain smoker. Everyone knows one, or knows someone with a great-uncle like that. We just should not turn him into a strategy. In the 50-year British Doctors Study of more than 34,000 men, smokers lost about ten years of life on average (Doll, Peto, and colleagues, 2004). A US study of over 200,000 adults backed that up and showed something hopeful too: quitting before age 40 wins back nearly all of the lost time (Jha and colleagues, 2013).

The thinking error here has a name: survivorship bias (the trap of looking only at the survivors and forgetting everyone who did not make it). The smoking centenarian gets the interview. The thousands of smokers who died at 62 sit in no talk show.

This is how health science actually works. It shifts probabilities across many people. It promises no single person a result. Franz is the lucky tail of a distribution: good genes, a good environment, and a solid dose of luck. Build a recipe out of his life and you make the exact mistake any serious health channel should avoid. You might as well ask lottery winners for their investment tips.

What About the Blue Zones Where Everyone Supposedly Lives Forever?

This is where healthy skepticism pays off. The famous old-age regions are often less a miracle and more a data problem.

Demographer Saul Justin Newman looked at the numbers behind Okinawa, Sardinia, and Ikaria. His finding: a lot of it rests on missing birth certificates, sloppy record-keeping, and signs of pension fraud. Only about 18% of the world's verified supercentenarians, meaning people over 110, even have a birth certificate. In the US, the figure is zero. In Greece, roughly 72% of the supposed centenarians turned out to be long dead. And on Okinawa, the poster child for vegetables, people eat the fewest vegetables and carry the highest body mass index in Japan, according to the Japanese government. Newman won the 2024 Ig Nobel Prize for this work, an award for research that first makes you laugh and then makes you think.

One caveat: Newman's work is still a preprint, so independent experts have not formally checked it yet. Read it as serious criticism, not the final word. The direction fits the pattern from the last section, though. Even apparent clusters of very old people often dissolve under a closer look. Anecdotes stay weak evidence, no matter how good the story sounds.

Does a Long Life Even Matter If You're Sick?

That is the right question. And it gets to the core. A long life is only half the deal. What counts is good years, not the raw count.

A recent Mayo Clinic analysis looked at all 183 WHO member states. The result: people spend an average of 9.6 years of their lives in clearly poor health, carrying a real disease burden (Garmany and Terzic, 2024). Since the year 2000, that gap has grown by 13%. In the US, it is the widest in the world at over 12 years. Women carry a gap about 2.4 years larger than men. We live longer, but the extra years are more and more often sick years.

Back in 1980, researcher James Fries hoped for the opposite. His idea: a good lifestyle could squeeze illness toward the very end, so you stay fit for a long time and decline only near the finish (Fries, 1980). Globally, that hope has not played out. That is exactly why I find sociologist Hartmut Rosa's point in the documentary so sharp. He sees a contradiction when the long life crowds out the good life.

I think he is right. About Franz, Rosa says something that hits the mark: Franz looks like the very picture of aging done well, yet he did none of it to avoid aging. It works in the living of it. That is the whole point. Franz never fought getting older. He simply lived well.

So the error sits not in longevity itself, but in its fearful, extreme version. Fight death every single day and you have already half lost. I left the Don't Die movement around Bryan Johnson when it started to feel like a religion. Once you start to believe, the science stops. Franz does not fight. He lives. And that is the synthesis the heated debate keeps missing: a long life and a good life are not enemies. Franz has both.

What Should You Actually Do for a Long, Good Life?

Stick to the basics, and take seriously the part that costs nothing. In the documentary, I said I focus on the fundamentals: sleep, food, movement. For me this is not about living longer. It is about staying healthy longer. That is a real difference. Those three shift your odds in the right direction in a measurable way, for almost everyone.

What Franz adds is the second half:

• Keep the people who are good for you close.
• Find something worth getting up for.
• Make peace with your own aging.

This pillar costs no money and sits on no supplement shelf. Yet in the studies it outweighs almost everything you can buy.

Yes, I use altitude training and red light myself. That is the bonus round. Skip the basics and jump straight to the bonus, and you are building a house starting with the roof. The smoking centenarian and the freshly-in-love Franz are both outliers. So build your life around what improves the odds for many, not around the rare exceptions.

I carry two pictures in my head. My grandfather, who took me hiking when I was small. That is how I want to be at 70. And my grandmother, who told me she was glad I kept moving, because she never did. Together they are my motivation. Not the fear of dying, but the appetite for good years.

How long do I want to live? I would be happy with 100. But please, 100 good years, with people I like. Not 100 years in a waiting room.
