He was born with a heart defect
If you think of Mitch Hedberg’s laidback stoner vibe, you might not think he came from the Midwest. (Or maybe you do, depending what you think of the Midwest.) Hedberg was born in Minnesota, and his family discovered early on that he had a heart defect. With him since birth, his mother Mary claimed his condition often caused him anxiety. Later in life, his heart condition may have contributed to his untimely death.
