Eagle can live 70 years, and it is the birthday star among birds. It is said that when the eagle lived to the fortieth year, its claws were numb and senile, its beak was hooked, its feathers were thick and dry, and its wings were difficult to fly. At this moment, the eagle is either willing to grow old and wait for death; Either renew the aging claws, beaks and feathers, and choose painful but hopeful regeneration. The eagle chooses to regenerate. It is extremely difficult to fly to the cliff to build a nest and live in peace. First, peck hard at the rock to make all the aging beaks fall off. After the new sharp beak grows, use the beak to pull out the numb claws one by one. Wait until the new claws are completely grown, and then pull out the old feathers with your claws. This process is naturally quite painful. But five months later, shiny new feathers grew, the whole renewal process was completed, and the regenerated eagle spread its wings and flew again, thus winning a brand-new life for the next 30 years. In the journey of life, there is no choice of "eagle regeneration"! At the critical moment of life, whether we are willing to sink or abandon the old and welcome the new depends on whether we take the initiative. Therefore, when people are old, they should not be pessimistic about the world, but should be full of spirit and sublimate the realm in order to achieve the goal of taking off again and making a difference in their later years. There are two 70-year-old ladies in Japan. One of them thought that this age had reached the end of his life, so he sat at home and waited for death. Another old lady began to practice a new project-mountaineering. As a result, the first old lady died quietly at the age of 75, just as she expected.
