One who has nothing to live for in his life would find his youth and “childhood” particularly precious. The romantic memory of the past is, in fact, not a discovery of the genuine greatness of childhood. but the awareness of the decline that comes with the middle age. Essentially, one only lives once, thus life is precious to everyone. However, if his life is dedicated to the cause of the masses, if he makes a point of doing something for the world every day. then he is always growing. Though old age. illness, and death are still inevitable, his cause the cause of the people is immortal, and he will experience the “eternal youth”.
