"Life begins at seventy", which is what American archivist Tanner said. He works hard. Although he is over 70 years old, he always feels that the fire of life is still very strong, and he can do many things. So the famous saying "Life begins at the age of 70" gushed out. I copied it in my notebook. Although I am over 60 years old, after reading this sentence, I feel very encouraged, as if I have just begun.
