【正文】
exists in a man of 60 more than a boy of 20 . Nobody grows old merely by a number of years . We grow old by deserting our ideals. Years wrinkle the skin , but to give up enthusiasm wrinkles the soul . Worry , fear , self amp。s heart the lure of wonders, the unfailing childlike appetite of whatamp。s a wirelestation : so long as it receives messages of beauty , hope ,cheer, courage and power from men and from the infinite, so long as you are young . When the aerials are down , and your spirit is covered with snows of cynicism and the ice of pessimism, then you are grown old ,even at 20 , but as long as your aerials are up ,to catch waves of optimism , there is hope you may die young at 80. Thank you! 英語演
