OK, suppose you have a heart attack. And the paramedics arrive and start doing CPR -- chest compressions to keep the brain perfused with oxygenated blood. They have to be done regularly, about 100 times per minute. So, how might you give a paramedic a rhythm to follow, to keep them on time? Well, one obvious way would be music; preferably something with a good strong beat. In fact, specifically (and ironically): the 1977 Bee Gees' hit Stayin' Alive.
Frankly, if I come to in the ambulance and the first thing I hear is Disco, my first thought will be that I died and went to Hell.
