How could looking at someone's earlobe tell you more about their heart than a conversation ever could? The answer emerging from research is... a crease. In this episode, I break down Frank's sign: the diagonal fold in the earlobe first documented in 1973 and now statistically linked to coronary artery disease, present in 64% of cardiovascular deaths versus 36% of others, and up to 8x more common in critically blocked arteries. Turns out your ear's been reporting on your heart this whole time.

You will never look at an ear the same way again. Including your own.
