I just got home from a phenomenal performance of Verdi's Requiem... and we happen to have a good blood pressure measuring device in the house... my BP measures 88/66. My wife's measured as expected. My usual pressure is 110/70. I actually had a long day at work, and prior to the concert I had a full meal with dessert. So, what gives? Surely it's just one data point, but how do you feel after a satisfying listening event?
