Classical music is good for the soul and maybe the heart too. Mice with heart transplants survived twice as long if they listened to classical music rather than pop music after their operation.
Masateru Uchiyama of Juntendo University Hospital in Tokyo, Japan, gave mice heart transplants from an unrelated donor which were therefore expected to be rejected. For a week following the operation, the mice continuously listened to Verdi's opera La Traviata, a selection of Mozart concertos, music by Enya, or a range of single monotones.
Mice exposed to opera fared best - they survived an average of 26 days, with those who listened to Mozart close behind at 20 days. Mice who listened to Enya survived for 11 days and the monotone group only seven days.
