 Heading up to Cripple Creek, stop by the Donut Mill. The Donut Mill has been a local and worldwide favorite since 1977. Call 719-687-9793 for easy directions. I'm Kareem Abdul-Jabbar. I learned about atrial fibrillation the hard way. My symptoms would come and go. Shortness of breath, fatigue. I kept going. Then I got so lightheaded, I couldn't. My doctor said I have AFib, so I'm about five times more likely to have a stroke.
