Music During Surgery? (e) 2-37 Scientists have found that the soothing effect of music benefits patients having eye surgery. Studies show that those who listened to their choice of music during surgery had a significantly lower heart rate and blood pressure than patients who did not listen to music. Heart rate and blood pressure of all patients increased the morning of surgery.. However, these measures of cardiovascular stress dropped significantly in the music group within ten minutes of tuning in, and remained low throughout the surgery. The stress from surgery was lower among the music patients, but their ability to cope was higher. These ratings confirm the benefits of music during surgery. It has also been noted in other studies that surgeons who play music of their choice during surgery feel that it relieves stress and improves their performance. In the words of one researcher, “If music was a drug, everyone would want it. Patients like it. It's cheap and effective, and has no negative side effects." NOTES: soothing 「(神経や感情を)静める」 cardiovascular 「心 (臓)血管の」cardio は heart の意. side effect「(薬物などの)副作 用」

(2) The leaders I talked to (not only made an effort to bring Met to together people from different backgrounds and perspectives but also took the time to talk to people outside their industry about their ideas. Rufus Griscom, serial entrepreneur and CEO and founder of Heleo, puts it this way: “Ideas are like people - they don't like to be isolated or treated jealously. They like to mingle, interact with other ideas.” “Like most young entrepreneurs, I used to be worried that if I shared a new business idea too broadly, someone else would run with it, andI would lose the opportunity,” he told me.
