1、My secret for staying young is simple. Put all attention to the part of your brain and keep it young and growing. Keep your mind awake and you'll stay young all over. These are exciting times. Take an interest in the world around you, and stick to learning at least one new thing every day. No matter how old you are, it's not too late to make your life more interesting. I know a housewife with no knowledge before she made herself into a well-known engineer. I know a retired electrical engineer who has become a highly-paid dress designer. Get over the idea that you are too old to go back to school. I know a man who entered medical college at 70. He got his degree with honours and became a famous doctor. Another man went to law school at 71 and now was an active lawyer. Staying young is easy for those, old or young, who live in the future. You can do it if you care enough to try. Keep your mind awake and active: that's the only way.
(1)、According to the passage, that people's brain of all ages remains young and growing is_B___.
A：impossible
B：a scientific fact
C：a secret
D：a wrong conclusion
