My secret for staying young is simple. Put all attention to the part of you---your brain and keep it young and growing. Keep your mind awake and you’ll stay young all over. These are exciting time. Take an interest in the world around you, and stick to(坚持) 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 who made herself into a famous industrial engineer(工业工程师).I know a retired(退休) electrical engineer who has became a highly-paid ceramin (陶器的) artist.
Get over the idea that you are ever too old to go back to school. I know a man who entered a medical college at 70.He got his degree with honor and became a doctor. Another man went to law school at 71 and now is an active lawyer(律师).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 you mind awake and active: that’s the only elixir(万验灵丹)
