but all eyes remain on diana it s now midday. i can t even swim! 18 hours into the swim. my muscles are going without oxygen and i m in distress while i m going. it s become clear that diana s condition is not improving. dr. broder has to do something drastic. he grabs his stethoscope zblooib michael s coming out. and plunges into the water. first he tries the inhaler again and then he returns to the boat and rigs this oxygen tank. he jumps back into the water, desperate to get diana some air. i m hyperventilating all the time. here we go, here we go. that s good. midnight, hour 28. diana has been swimming with bad asthma for nearly 12 hours and
