you don't have to run back and forth to the doctor all the time. >> how does it work exactly? >> well, essentially the same way they've always worked only it's taking the computer out of the device you're wearing. so any time you have a heart monitor, there's a sensor and a computer. now we all carry computers in our pockets. so they are building sensors that are small enough to be woven into fabric which cuts down the barrier to entry for any of us too lazy to go buy a heart monitor, right? >> it is a little cumbersome, too. it's not super comfortable, as well. one of the t-shirts we've been looking at. you can wash the t-shirt and take it out. but do people really know what to do with the information? it's great to have information, but do we all know what to do with the information once we have it? whether it's our heart rate or anything else? >> i think that's the struggle. we're going to have large amounts of data in these data silos that are all biologics. and we've got to work with our physicians to understand how to interpret that data and act on that data. otherwise it's garbage in equals
