I worked on a device that used kirlian imaging to scan your body's health using only "finger prints". The founder of the company could tell from no prior knowledge that I had to pee at the time of the evaluation and I also had a back injury a few years ago. Lot's of people would argue this isn't scientific, but we used known diagnosis from current medical practices related to heart disease, we were able to establish 95% confidence whether a person was at risk of cardiac failure just based on their finger tips.
