I’m 36 and often get told I look younger, but a ‘biological age’ test said I’m almost 42

  • I got my “biological age” tested by researcher David Sinclair’s new startup, Tally Health.

  • I’m 36 with generally healthy habits, but the direct-to-consumer kit told me I’m almost 42.

  • The concept of biological age is somewhat controversial, and I feel shamed for aging poorly.

When I was invited to have my “biological age” tested at a media event last month by the new company Tally Health, I RSVP’d yes.

Sure, I was curious to learn how the age of my insides squared with the age on my ID, but really it was the promise of free coffee, pastries, and sweeping city views from the Ritz-Carlton’s swanky penthouse suite that drew me in.

Unfortunately, I’ve since learned, possessing the motivations of a college student (free food!) does not mean preserving the DNA of one.

When my results came back weeks later, I discovered that despite being born a little over 36 years ago, swimming daily, never smoking, and being unable to enter a bar or even exit a Whole Foods without being carded, my so-called “biological age” is nearing 42.

Here’s what the experience was like, and what I think consumers should know before going through it themselves.

Tally Health looks at DNA methylation

Taking the TallyAge test was like an at-home COVID test, but instead of swabbing your nostrils, you swab your cheek. You then seal the sample, send it away, and hope for the best — or, in my case, chug my first coffee of the day since you can’t eat or drink in the 30 minutes prior to the test.

While there are many ways to estimate biological age, Tally Health looks at DNA methylation, or changes to genetic material that tends to occur with age. While the company, helmed by Harvard longevity researcher David Sinclair, isn’t the first to offer this type of direct-to-consumer biological age testing, it says its proprietary machine-learning model is superior, having been trained on “the largest and most diverse consumer DNA dataset” to date.

Tally Health also offers monthly “memberships” ranging from $129 to $199 so you can repeat the process and, ideally, stop or even reverse aging by making the company’s recommended lifestyle changes (and taking their supplements), Sinclair told me.

But first, you have to know your baseline.

I suspected mine would be about 36. After all, past indicators have suggested I’m age-appropriate, even youthful. A 2021 blood panel from my doctor raised no red flags, I placed in the top 5% of swimmers in last summer’s New York City triathlon, and makeup artists and broadcast hosts have recommended my wrinkle-free skin. Visit me over the holidays after a few days with my parents, and you’ll see I can act like a pouty preteen, too!

Sure, I have a few beers near-night (unless it’s January), sit for nine hours a day at my desk job, and consider myself a “healthy” eater because I order my Shake Shack wrapped in lettuce. But don’t we all have virtues and sins?

Apparently not: When I clicked through to view my TallyAge via an online portal, I learned that my “biological age” was nearly six years older than my chronological age. Not only that, but I was also in the abysmal 4th percentile — in other words, 96% of my 36-year-old peers have organs more spritely than mine.

My husband and best friends were shocked and even humored. I was angry.

Should I have frozen my eggs? Opted for ignorance over bliss and refused to take the test to begin with? Felt even more shame about the habits I’ve struggled to change? Or, as a colleague asked, is it all just a bunch of “classic Silicon Valley BS?”

The lifestyle recommendations that were supposed to slow or reverse aging were predictable

When I called Tally Health’s director of research and innovation Adiv Johnson, he was confused about missing my 40th birthday, he thought that my placement in the 4th percentile was skewed.

While the pool of 8,000 cheek swabs the company used to help build its machine-learning model was diverse, he said, it also consisted of the kind of people who had to sign up for the company’s waiting list to be included.

In other words, affluent bio-hacking geeks eager to brag about their Benjamin-Button status, not the average American who has limited access to plant-based foods, lacks quality healthcare, and work nights.

Still, the Tally Health team pushed me to view knowledge as power. Genetics determine less than 10% of longevity, they like to say, and the rest is up to lifestyle (if, of course, you have the privilege to change it).

“If you haven’t taken the test, you’d still be that age. Knowing that number is not making it true – it was always true,” Sinclair tried to comfort me over Zoom between sips of matcha and swallows of supplements.” Now at least you can take action.”

But some of the actions the Tally Health platform prescribed based on a “lifestyle survey” I filled out after receiving my results are easier said than done, and many of the others didn’t require a sleek test to spell out.

For example, because I rated my social satisfaction and feelings of purpose as mediocrity, the platform told me I should – wait for it – “increase life purpose” and improve my social life. Other recommendations were more practical, but not surprising: Eat less red meat and more fish, sit less and sleep better, drink less and meditate more.

While I did appreciate how the platform tiers their recommendations – for example, I could make a few smaller, more manageable shifts to my diet, sleep, and movement or one bigger change to my alcohol intake for potentially the same health span-lengthening results – I wondering why a test that’s apparently so specific to my personal DNA dished out advice so, well, generic.

Tally Health supplements

Matt Kaeberlein, director of the University of Washington’s Healthy Aging and Longevity Research Institute, told me it’s because, like other direct-to-consumer kits, Tally Health tests aren’t FDA-regulated, and so can’t dole out medical advice.

“That’s part of why everybody who’s done these tests feels a little bit let down in the information you get back, which is, ‘Eat more vegetables, exercise more, get better sleep,'” he said.

Some people may find learning their biological age to be motivating. I found it anxiety-provoking.

Kaeberlein also assured me that while DNA methylation is a highly-regarded way to gauge how well or poorly you’re aging, it’s not the only way — and it’s flawed.

“These methylation tests are really measuring one small piece of the type of molecular changes that go along with aging, but you could just as easily build a biological age test off of functional measures like grip strength or how fast you can run or how much weight you can bench press,” he said.

Kaeberlein also takes issue with the rush to commercialize complicated – and, in many ways, nascent – ​​longevity research. Sinclair’s work, for one, draws on rat studies that have yet to be replicated in humans.

“I’m a little bit concerned it’s going to be harmful to the reputation of the field in the long run, because when you over promise and under deliver, people tend to remember that,” Kaeberlein said of biological aging tests in general.

The kits also aren’t cheap, and while some people may find they motivate positive behavior change, he said, others adopt the “screw it” philosophy and develop anxiety. Perhaps it’s a sign of maturity that, for me, the free coffee wasn’t worth it.
