I had a stress test once. It was more of a routine test because my family has a history of heart problems. Being a runner, I thought for sure that I would make those doctors miss lunch I was able to stay on the treadmill for so long. It really is simple. They start an IV in your hand and inject some magical die so a machine can see pictures of your heart. Then they put you on a treadmill and make you walk. Easy, right? Well, no because they put quite an incline on the treadmill. It’s tough and this overconfident runner didn’t stay on the treadmill nearly as long as he thought he would.
