Someone is Watching You?

Although the idea has been around for many years, an International team appears to have come up with some innovations for fitting a 'smart toilet' to monitor health over time (https://www.theguardian.com/society/2020/apr/06/magic-toilet-could-monitor-users-health-say-researchers). The system of sensors and detectors can apparently be fitted relatively cheaply to existing loos and can monitor conditions such as diabetes, urinary tract infections and inflammatory bowel diseases (it even takes pictures of stools and uses AI to classify them). Of particular interest, is the device's ability to recognise who was using it. This is either via a fingerprint scanner on the flush handle or from the pattern of creases in the anus (the 'analprint).
