I think one of the advantages of living in a first world country is the availability of all the modern and state of the art medical equipment. I know healthcare without medical insurance can cost you a fortune but knowing that anytime you need emergency and intensive care, it is available. For instance, if you have a heart problem like unexplained chest pain, the ekg, electrocardiogram, can be used to determine what the problem is. EKG is a test that checks for problems with the electrical activity of your heart. EKG is just one of the many breakthroughs in medicine that helps people find answers to their health problems. It is always important to take care of your health and take any precautionary measures especially if you aren't feeling well. Talk to your doctor if you need professional opinion about your situation!
