I want to know the answer to the following question:
How old was Schwarzenegger when he moved to the U.S.?
All the background I'm provided with is that "Schwarzenegger, who dreamed of moving to the U.S. since the age of 10, and saw bodybuilding as the avenue through which to do so, realized his dream by moving to the United States in September 1968 at the age of 21, speaking little English.". Is that enough to answer the question?
Answer: yes
