Treadmill 20:00 
Echo stress test at the cardiologist's office. Chest exfoliated, 15 tabs stuck to skin, harnessed to machine, get doppler imaged, then hop on treadmill, go until HR > max (that was the 20 min), then back on the table and get doppler imaged again. Verdict: I'm too healthy to be in his office, but he wants to see me in another year nevertheless. The issue is the mitral valve, which is still holding, like the boy with his thumb in the dike.
