When you leave school，you can breathe sigh of relief and leave learning behind，right？Wrong！Learning should last a lifetime. You exercise your body to stay strong，and you should exercise your mind to stay sharp.

An English idiom says，“You can’t teach an old dog new tricks.” But scientists have discovered that isn’t true. Older people can learn，and they should，in order to keep their brain active. Now a new trend has begun in several states in the US that encourages learning. Adults can attend One Day University. They can spend a Saturday or Sunday hearing four 70-minute lectures. Each one is given by a top university professor. One of the original participants said，“It’s like a health club for the brain.” Also，universities like MIT have made all of their courses and lectures available online for free！Libraries offer learning programs too. With so much available，there is no excuse not to learn!

Learning is a habit. Don’t leave it behind after you leave school. On the website lifehack.org，author Scott Young mentions several things to help you.

Always have a book. It doesn’t matter if you read fast or slow. Just read. If you read just one book a week，you’ll read 52 over the course of a year. Think of the knowledge you’ll gain!

Practice it. As you read，do something with what you’ve learned. Don’t just enjoy the mental exercise. Use the knowledge. If you read about painting，try it!

Make a “to learn” list. Compose a “to learn” list for yourself. Maybe you want to speak better English，play the piano，or cook French food. Whatever interests you，put it on your list and then make the time to do it.

Teach others. Whatever you learn，teach someone else. You’ll not only help others but also understand what you’ve learned.
