Have you heard about the guy who's trying to live forever?
Bryan Johnson was a tech founder who made $800 million when he sold his company to PayPal in 2013.
Dude's still only 48, and has become convinced that there's a way to stop the human body from aging. He formed a team of 30 medical professionals to 'build the world's best health protocol', and in doing so, "I became the most biologically measured person in history and achieved the best biomarkers in the world. Quantitatively, the healthiest person on the planet," he wrote on his website.

Secrets of the 'immortal unc'
Part of Bryan Johnson's health protocol is concerned with blood glucose, also known as blood sugar.
His blood glucose is one of the headline stats he tracks. He says his own is "lower than 98% of 18-25 year olds."
Generally, people track their blood sugar when they're trying to manage diabetes or prediabetes, which are conditions that can lead to some pretty scary outcomes if left untreated.
But recently, people have been tracking their blood sugar for wellness reasons — and apparently, to live forever.
Why would you track your blood sugar if you're not ill?
In a nutshell, because it's easier to do it than it used to be.
Previously, diabetics and those with pre-diabetes had to track their insulin with daily finger-pricks. But then over-the-counter continuous glucose monitors were approved by the FDA in the United States, and so people who weren't living with disease could more easily track their blood sugar if they wanted to.
These wearables, known as CGMs, automatically measure your glucose every few minutes. Basically you stick a small sensor to your skin and it continuously measures the glucose level in the fluid just under your skin and tells you how you're tracking via an app.

It's not just food that can make your blood sugar spike: stress, skipping meals, sedentary lifestyles, and hormones can all play a role — leading to short-term fatigue and brain fog, and long-term issues including weight gain, diabetes, and heart disease, according to Johns Hopkins Bloomberg School of Public Health.
There's also an influencer element:
The Glucose Goddess is an influencer who wrote a New York Times bestselling book about steadying your blood sugar to "Cut cravings, get your energy back, and feel amazing." She has six million Instagram followers.
Gwyneth Paltrow went live on Instagram wearing a monitor, which led to public conversation too.
Why are you telling me this, Spaceship?
The first over-the-counter CGM that was approved is called the Dexcom Stelo Glucose Biosensor System, known more colloquially as the Stelo. And Dexcom is in the Spaceship Universe Portfolio at the time of writing (17 March 2026).
So each time you see an influencer, someone at the gym, or a diabetic using a Stelo, as a Spaceship Voyager you'll know you have indirect exposure through a diversified portfolio.
We're finance professionals, not health professionals, so we can't tell you if tracking your blood sugar is going to help you live forever. And when we added Dexcom to the Spaceship Universe Portfolio in 2024, it wasn't just because of the Stelo, but also because diabetes is one of the world's fastest growing health problems, with the International Diabetes Federation estimating that by 2030, one in nine adults will have diabetes.
Investing where the world is going
Some of the Spaceship Voyager portfolios invest in companies we think meet our Where the World is Going (WWG) criteria, which includes a focus on long-term trends.
We believe Dexcom is WWG because it has exposure to the Healthcare WWG trend. This trend is focused on companies that sell products to meet the medical needs of their customers, including individuals, businesses, and other healthcare providers. Their products may be digital, wearable, personalised, or medication — or they may be the software or hardware that underpins these.
One ring to rule them all
And, if you or any of your mates wear an Oura ring, you have further exposure: in November 2024, Dexcom and Oura announced a partnership to share data between Dexcom's sensors, and Oura's wearables and app.

They saw it as a win-win: to expose each company to the other's customers, and for Dexcom to give Oura a $75 million cash boost for a stake. For customers, the partnership should allow a more complete view of their health and how each influence — from sleep, activity, and now blood sugar — impacts each other.
Investing with the Spaceship Voyager portfolios means you could get exposure to the long-term trends and companies shaping the future. If CGMs help people live forever, we've got exposure. But if they just help people with diabetes feel better, we think that's a pretty good deal, too.
