Koreans say slow music delays Delta Covidmain
The South Korean authorities have ordered gyms to slow down their music in order to delay the spread of the Delta variant. The idea is that people breathing faster spread more droplets.
Under the new rules, music in gyms must play slower than 120 beats per minute during group exercises.
Treadmill speeds are reduced to 6kph and table tennis can be played only in singles, not doubles.
Showers and saunas have been shut.
