Due to the tragic history of heart diseases in my family and some recent chest pain I was feeling my wife finally persuaded me to do some check-ups. I ended up doing three test the last one of which was the most detailed one. Basically they insert a tiny tube into you, push it all the way to the heart and then pump contrast liquid and take pictures/videos to see if all your arteries are OK. I was relieved to find out that I'm just fine. At the end of the test I got a CD containing videos they took during the exam. This video is the proof that I have a heart ;)
