Just do the math. In the next 50 to 75 years, people will be living to be 130 and 140. They'll be working until they're 100. It's incredible.
Now I come to 75 years of age, I think what's most important in life is your conscience. If you told a lie and made other people suffer, I think that's very difficult when you reach this age. Mstislav Rostropovich
