ah, yeah, the nurse said they can attach a recording device to you to monitor your heart rate and anomalies, pick up on weird crap like arrhythmia and heart murmurs if you have them. Some people carry them at work from time to time but you can't tell who; a few people here have them permanently for one reason or another, but of course the medical office here won't disclose any information aside from that there are such people in this building.
