Until I can ride my bike again. 7 weeks out of Aortic valve replacement. Have to give my chest a chance to heal. It's 'killin' me (not riding). I was riding 25 miles a day the last month before surgery. Got 800 miles in the spring / summer. Was hoping to get in 1000, but the doc said it was a best to have the surgery while I was still healthy (just rated at severe aortic valve stenosis, but no symptoms), so we got 'er done. That first month after surgery was pretty rough as the ventilator allowed my lungs to fill with a lot of fluid. So yackin that up was pretty painful. Doing good now, just gotta wait. Hoping for a mild winter!
