#Stillstanding 128 in an auditorium at the University of Malaga right after guest lecturing about my new book #SoundActions, listening to a pretty soft ventilation system and traffic from the highway outside and watching the #visualrhythm of the empty seats in front of me. My sports watch reported a 38 BPM pulse; that sounds incorrect! Then I think it is better to trust the accelerometer data, which shows a peak at around 76 BPM.
