Toscanini's long career

The famed Italian conductor Arturo Toscanini was born in 1867 and died in 1957, when I was two years old. He was well known in his latter years as conductor of the NBC Symphony Orchestra, whose baton he assumed at age 70. He continued to conduct right up until 1954. Given that he debuted as conductor in 1886 at age 19, his career lasted an extraordinary 68 years. If I were to teach that long, I would be retiring at age 100.
