To make the brain work more efficiently, neurologists and psychiatrists advise challenging it in different ways. You can study a foreign language, constantly improve your skills in solving math puzzles or riddles, or even set aside some time for online puzzles.

Solving puzzles is an interesting way to test your ability to think outside the box, as well as just an interesting exercise in logic. An interesting puzzle about a basket of four pears is gaining popularity online.

The conditions are as follows: there is a basket with four pears in the room. There are four people standing near the basket. Each took one pear, and at the end there is one more pear left in the basket. How is it possible?

Give yourself some time to think and don't get upset if it takes you more than 10 seconds to solve a puzzle. Naturally, such tests can only be categorized as "mental" tests. They cannot define the level of your mental abilities and IQ. So just consider such puzzles as a way to train your brain.

Now it's time to reveal the cards. The correct answer is that each of the four people present took one pear, and the last one took the remaining pear along with the basket.

According to WebMD, medical research shows that training the brain with such puzzles potentially reduces the risk of neurological disease, dementia or Alzheimer's disease.

That's why games, puzzles and other types of brain training can help slow memory loss and prevent other mental health problems.

One study involved more than 2,800 adults age 65 and older. They underwent up to ten hours of brain training for five to six weeks. The people who underwent the training showed long-term improvement in these skills. They even had improved memory performance.
