Ya?l:Well，focus，is soon Don get here？We can begin the program. Don:Hi,Yael,oh,sorry,I'm late. Y:Are you OK? D:I was carrying some stuff to my basin last night and it sprained my ankle.It's still swollen. Y:I have just to think to help. A little Mozart please？ D:Wait，wait，hold on.What does Mozart have to do with my sprained ankle? Y:Maybe it'll help.Studies have shown that Mozart is therapeutic,it can help lower blood pressure and reduce pain in patients on the mend. D:Any music or just Mozart? Y:Good question.Mozart was a sickly guy, always battling some illness or infection, so he may have unintentionally composed music that helped him relax and feel better. D:That's interesting，but how can we know that's true？ Y:Well，a Harvard surgeon named Claudius Conrad did a simple experiment. He gave earphones to ten patients recovering from surgery. Five listened to Mozart, and five heard nothing. The patients that listened to Mozart had lower blood pressure, less need for pain medication, and had a drop in stress hormones. They also had an increase in pituitary growth hormone, which could work as a sedative. D:Interesting，but what if you hate Mozart，what if your favorite music is heavy metal？Was that still help you heal？ Y:That's the next step in research.
