Train your brains!

Mental exercises such as crossword puzzles, brain teasers, chess, or card games help keep the mind working in top shape. This helps build what is called a "cognitive reserve." Formal education also helps build a person's cognitive reserve. In fact, each year of education reduces a person's chances of getting Alzheimer's by an average of 17%. Scientists believe this is because people with a large cognitive reserve are better able to adapt as neurons are killed by the disease. The more neural connections you have, the longer it takes for the disease to make a significant impact.It's important to note that mental exercise cannot help significantly once Alzheimer's has already set in. A person must have a lifetime commitment to learning in order to build up his or her cognitive reserve. It is probably not possible to completely prevent the disease in genetically susceptible people, but it is possible to delay the onset so that it will not occur in the person's lifetime.

In conclusion, study a lot! Let's also have some fun with this brain teaser which will help you to wake your brain up:

Greatest Area

A farmer challenges an engineer, a physicist, and a mathematician to fence off the largest amount of area using the least amount of fence.

  • The engineer made his fence in a circle and said it was the most efficient.


  • The physicist made a long line and said that the length was infinite. Then he said that fencing half of the Earth was the best.


  • The mathematician laughed at the others and with his design, beat the others. What did he do?


The answer? ... SOON

The answer to the brain-teaser is:
The mathematician made a small fence around himself and declared himself to be on the outside.

Isn't it clever?
