Our brain is the most important part in our body. It helps us to think, speak, feel, and move. It’s no wonder we need to look after it and just like the rest of our body. We need to keep it exercised to keep it healthy.
Our brain is made up of 86 billion neurons—or nerve cells (神经元), but as we age, some of these gradually die off. In serious situations, nerve cells in different areas of the brain become hurt and finally die, leading to a condition called dementia (痴呆), which influences a person’s ability to think properly.
It’s a good idea to train our brain by learning ways to increase our memory and intelligence. For example, solving crossword puzzles (字迹) can be really helpful. Dr Catherine Loveday, who’s a neuropsychologist, thinks learning a second language is also great for the brain, as it requires us to switch (切换) between languages, making our brain stronger.
However, if you don’t speak another language, there are still ways to train your brain. If you’re right-handed, try performing tasks like brushing your teeth with your left hand to improve your brain.
The main reason we do these exercises is to keep our brain active. It can help to develop additional abilities to help protect the brain against the loss of memory or thinking. Dr Catherine Loveday, says, “Even if people take up languages or other activities later in life, it will provide them with a degree of protection.” As an old saying goes, “It’s never too old to learn.”
According to a study, people are surprised to know about that eating chocolate might increase our ability to get and use knowledge. It could improve how you learn and use information. Although it might not be good for the rest of your body, at least it could make you a brain box!

At night, you fall asleep while listening to beautiful music. In the morning, you are woken up by the singing of birds outside. You can enjoy all of these things because of one important organ — the ears.
You may wonder: how do the ears work? The ear has three different parts: the outer ear, the middle ear, and the inner ear. The outer ear is the part you can see. It collects sound around you. The sound then travels down to the middle ear, the inner ear and then to your brain.
Your ears never stop working, even when you are asleep! Your ears continue hearing sounds, but your brain just ignores (忽略) them. That’s why you might sometimes wake up suddenly in the middle of the night — your brain heard something but you don’t know what it was since you were asleep.
But ears do more than hear. They help you keep your balance, too. In the inner ear, there are organs that are filled with liquid (液体) covered in small hairs. When you move your head, the liquid and hair move, too. They send messages to your brain about the position of your head.
More surprisingly, ears even help with tasting food. Of course, you don’t actually taste food with your ears. But there are nerves (神经) running through the middle ear that connect the tongue to the brain. If something wrong happens to your ears, you might have a hard time telling different flavors apart according to People’s Daily.
The ears are truly important organs with many functions. Everyone should make sure to protect their ears as well as they can.
