Well, here's what I can tell you. A couple of years ago my neighbor had a heart attack, and he was fortunate enough to survive the heart attack, but he had a pacemaker installed. And he didn't really know exactly what I did for a living, but he was telling me he had this really odd experience. He was at the doctor's office and they were adjusting the pacemaker. And he could see his pulse on the screen, and his pulse was like 65. And they put something over his chest, and then they turned some knobs on a computer. And they turned his heart rate up to 75 beats per minute, and then they turned it up to 85 beats per minute. And with him just sitting there, his heart was changing beat patterns wirelessly. And I kind of chuckled because I said that's a lot of what I work on because he said, can you imagine if somebody would do that outside of a doctor's office? That's the kind of thing that is doable. The difference between reality and what's in Homeland, or what we see in the movies, is dramatized, but the potential for that is there. And it's not because of security, it's because that's what those devices are supposed to do. They're supposed to change people's pulses, they're supposed to keep people alive. Just like if you use a defibrillator on a person when their heart is beating, it will stop the heart from beating. These things occur. Are they realistic, can those attacks be performed from across the country? Absolutely not. You have to have very close physical proximity at this time for those things. In the future, though, as we have pacemakers interface with an iPhone, with other types of technology, this changes things dramatically. And I don't know what the future holds, in that case. And that's why we have to get this right the first time and not just force this technology into the marketplace because we think it's cool or because we think it's trendy. It has to be done right and it has to be done safely.
