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!
