The eagle has the longest life of its group．It can reach up to
70years．But to reach this age，the eagle must make a hard and
painful decision．
When an eagle reaches near 40，its short sharp beak becomes
bent（彎曲的）．Its long and once flexible（靈活的） talons
can no longer catch animals or birds for food．And its old and
heavy wings with thick feathers on its body make it difficult to fly．
Then，the eagle has only two choices：to die or to go through a
painful time of change which needs five months．
When the eagle feels weak and is about to die，it goes to a
place far away on the top of a mountain and sits on a nest．For a new life，the eagle knocks its beak against a rock until it pulls its beak out．After pulling it out，the eagle waits for a new beak to grow．And then it pulls out its talons and old feathers．It takes the eagle five months to complete its change and get a new life．We can call it its rebirth．So it can live for 30more years．
Like the ea gle，we human beings sometimes need to make some change to get out of our difficulty．In miserable condition，we have to change our ways of life．The changing may be very painful．But sometimes we have to throw off our old habits，memories and traditions．We can't go on with all our past burdens（重負）．
