My name is Ben Greenfield, and on this episode of the Boundless Life Podcast.

People don't actually really know their blood pressure at all. You probably don't really understand your blood pressure, and it's because the cuff is... Number one and number two causes of death are basically related to arterial health and blood pressure. There's no device on the market today that can do that. This is the first device in the world that's available to consumers that can accurately measure blood pressure without calibration from a cuff.

Welcome to the Boundless Life with me, your host, Ben Greenfield. I'm a personal trainer, exercise physiologist and nutritionist, and I'm passionate about helping you discover unparalleled levels of health, fitness, longevity and beyond.
I spent 20 years measuring and optimizing everything about my body, deep performance metrics, cold stress, heat stress, sleep scores, blood panels, peptide protocols, testosterone, telomeres, VO2 max, you name it. And somewhere in the middle of building what looked like perfect life, I almost lost the life that I was building it for. Boundless, the man who became human with a brand new feature documentary that follows what happened when the optimization framework that I spent two decades constructing ran headlong into the things that metrics could never measure. My marriage, my sons, my faith. The private archive footage in this documentary has never been seen publicly. Some of it I debated even including at all. It shows basically the worst of what happens when longevity becomes the ultimate goal and how you and I can turn that around to become fulfilled by what's truly important in life. Now this is not just another biohacking film. It's an honest look at what it costs to chase the ceiling on human performance told through real footage of one family, my family finding that out. And I'm giving you the chance to join me for the brand new live premier tour of this new film In A City Near You. Here's what the night looks like. You watch the film, me and my family in a theater, and then you experience a live episode of the Boundless Life podcast on stage with open Q&A, real questions, no filters. My wife, Jessa, and my sons, River and Taryn, will be there with us as well. VIP ticket holders get to join for an exclusive after party with upgraded food and drinks. This Boundless Life tour kicks off in LA on July 24th, Austin on August 20th, New York City on August 6th, Miami coming down the pipeline, London coming down the pipeline, more cities to be announced. Tickets are on sale now. Grab them now before they're gone at boundlessdoc.com. That's boundlessdoc.com and I hope to see you there.
Blood pressure is one of the most important signals of overall health. It's a major contributor, as you will learn much more detail about in this podcast to leading causes of death worldwide, including heart attacks and strokes and more than 1.7 billion people worldwide and nearly 120 million Americans have hypertension. And it's kind of ironic because blood pressure monitoring has like barely changed in 150 years, in terms of the technology, you know, the old school uncomfortable cuff that is used to measure it. So my guest today is Tom Moss and Tom is part of the team that has developed a new way to measure and track blood pressure from your finger. The ring that they built is called the Signal Ring, the Signal Ring. Tom is the CEO of the company Vital Signals. You'll learn his story in today's show, but he has assembled a team of experts who specialize in technology and blood pressure management and measurement. He's been able to pull something off at Signal that nobody has ever done before.
bengreenfieldlife.com/signalspodcast is where the show notes reside, where you'll be able to get a ring when these things are released. I'm wearing one right now.
bengreenfieldlife.com/signalspodcast, and let's go talk to Tom.

**Tom Moss** (4:51)
Thank you for having me. I really appreciate it.

**Ben Greenfield** (4:53)
Yeah. Before we started recording, you're holding up the rings on your finger, your self-quantification rings to rule them all. How many are you sporting right now?

**Tom Moss** (5:03)
Three total, but only one that matters.

**Ben Greenfield** (5:06)
Okay. Only one that matters. Obviously, one I would assume is the wedding ring, right?

**Tom Moss** (5:11)
That's right.

**Ben Greenfield** (5:12)
That's important. I wound up just tattooing mine on.
And then the one that's important is the one I want to talk about.

**Tom Moss** (5:20)
I should probably say that the wedding ring is important too. Sorry to interrupt.

**Ben Greenfield** (5:25)
Well, your wife might listen in. Hello, Tom's wife. It's always better for that.
