According to this news clip the body temperature pattern can reveale if you are in love. The consequensies for a couple could be devastating if a free test will be available in future. There could be terrifying options for bodies which are functioning significantly different and test results will segregate them to a lonely life.
On the other hand there could be different use for this kind of checks! For example there maybe is a difference in temperature when you are in a PRACTICA mode and your brain is monitoring your movements and planning the coming steps compared to when your are actually dancing. I think that in the DANCING mode your brain is in a different state and the emotions are more active, you feel your dance. This could produce a different thermographic pattern, noticable in an external device. It could reveal at what level your dancing shifts back to practica level, when you need to think how to dance. This shift is different for different dancers and it goes together with the skil level. The more skilled couple the later the shift comes!
So in the future the organicer asks you to dance, points her mobile phone at you and places you to level x on the workshop weekend!
Here you have the link to the love version of the body thermography test:
