"你真正完全生活的时间只有从三十岁到六十岁。年轻人是梦想的奴隶;老年人是悔恨的仆人。只有中年人所有的五种感官都在智慧的掌控之中。"
— Theodore Roosevelt
Simplified Meaning:
People live their best lives between the ages of thirty and sixty. Young people are focused on their future dreams and older people often think about their past mistakes. Middle-aged people are able to understand life and make the most of it.
