Sure, disco sucks...

...but it could help to save your life. Well, one disco song, specifically:

U.S. doctors have found the Bee Gees 1977 disco anthem "Stayin' Alive" provides an ideal beat to follow while performing chest compressions as part of CPR on a heart attack victim.

The American Heart Association calls for chest compressions to be given at a rate of 100 per minute in cardiopulmonary resuscitation (CPR). "Stayin' Alive" almost perfectly matches that, with 103 beats per minute.

CPR is a lifesaving technique involving chest compressions alone or with mouth-to-mouth rescue breathing. It is used in emergencies such as cardiac arrest in which a person's breathing or heartbeat has stopped.

CPR can triple survival rates, but some people are reluctant to do it in part because they are unsure about the proper rhythm for chest compressions. But research has shown many people do chest compressions too slowly during CPR.

In a small study headed by Dr. David Matlock of the University of Illinois College of Medicine at Peoria, listening to "Stayin' Alive" helped 15 doctors and medical students to perform chest compressions on dummies at the proper speed.

Five weeks after practicing with the music playing, they were asked to perform CPR again on dummies by keeping the song in their minds, and again they kept up a good pace.

The article makes no mention as to whether or not the ballad "How Deep is Your Love?" has any possible medical applications.
