From The New Brain, by Richard Restak, MD, a work of popular neurology.
[Restak is writing of amusia, which he defines as an inability to distinguish music from other sounds]
“The revolutionary leader Che Guevara suffered from amusia. When attending dance parties he had to rely on companions to help him distinguish between a tango, with its slow gliding movements and abrupt pauses, and a gentle Brazilian samba.”
He probably wasn’t so good at what Methodists are supposed to think dancing is like, either.
