       A friend sent me a link to the following article, which mentions th
       synchronization of heartbeats among choir members.
       
 (HTM) Neuroscience of Singing
       
       This reminds me of two songs:
       
       1. "We are one world, one voice, one heart beating."
 (HTM) One World One Heart Beating by Oona McOuat in 2012
       
       2. "All hearts are beating as one."
 (HTM) Way of the Heart by Ruparahi in 1983
