Long time cyclist who lost a quarter of lungs to a 6 year struggle with undiagnosed ABPA(Allergic Bronchopulmonary Aspergellosis). Came close to punching out after losing 3 units of blood due to disease/med complications that caused a blood vessel to break. You haven't lived until you're in extremis from blood loss, every vein has collapsed, and the medicos are struggling to run a transfusion line into you. Many thanks to the ER/ICU teams at Boulder Community Hospital who saved my life! Now every time I ride is a pure gift from the Good Lord.
