Bryan Johnson uses a cheap spirometry device to track his lung capacity as part of his anti-aging work. He blows into it three times to measure how his lungs respond to swimming, running, and other therapies. A UCLA baseline test measured his diaphragm strength and gave him numbers to compare against.
I've been spending millions of dollars on anti aging and trying to find things that are easy to do at home and also low cost. Our lungs are among our most important organs and knowing if my lungs are improving or declining is very important. This device has helped me understand how things are going. This device is low cost, it can be bought by anyone and it's used for spirometry. And so you put your mouth on this device and you blow as hard as you can and you're able to with three trials, get scores and measure the status of your lungs and then the progress if you're doing any therapies. So for example, if you're swimming or running a lot, you can see what changes in your lung capacity. But I use this on a regular basis because we do a lot of therapies to try to strengthen my lungs. I did a professional grade assessment at UCLA looking at all sorts of things, my diaphragm strength, many more things I could do than this device to get a baseline and then we monitor on a regular basis at home with this.
