We do a lot with the elderly. We poll them about every three years. They use the Internet, but a lot of them aren't there yet in terms of using applications. They quite like devices that sit on their little lampshade. They go to it; they use it; they're done. And they do very well with the phone piece. They just plug it into the phone. If they have a jack, they can use it.
In our particular program, because there are such huge cost savings, we buy the device and we pay the charges for the long-distance calls that would be incurred over the phone line. It's minuscule; they're only online for a couple of seconds when they download their data. So there's a huge cost saving, and we provide that service at no charge to the patients.
Automated calling is the same for them. Interestingly, 45-year-old men with heart attacks are the group that don't like to use automated calling—no surprise—and they're going to be back. But, broadly, people use these systems because they're very easy. We watch, and we think in the next five years we will begin to develop some apps for the 55-year-olds now who will get their heart disease because they will probably want them. Right now the group that we see doesn't, and we just continue to monitor that. They use smart phones. They're just not quite there with it yet as a device to monitor their health.
