I was studying abroad and I met this guy who went to Yale, and I don’t even remember how we got into the conversation but he incorrectly stated that the heart was located on the left side of the chest. I said “It’s actually more in the center of the chest, just slightly left. Common misconception.” To which he replied “Uhm, no, it’s on the left. Why do you think we put our hand over the left side when saying the pledge of allegiance?” I explained to him that my father is a cardiologist and it’s definitely in the center of the chest, he then very condescendingly replied “Your dad is a cardiologist and you still don’t know where the heart is?!” A quick google image search on my phone shut him up real quick.
