Tips for developing an exercise plan for your brain
You know that eating a sensible diet and getting plenty of exercise help your body healthy and strong. But did you know that there are ways to make your brain healthier and smarter?
Studies show that when the brain is compelled to do something new, it creates new neural pathways（神经通路）. The more pathways you have, the faster you can think and the better memory you will have.
Ten steps toward a smarter brain
Limit your TV time
Watching an average TV show requires very little brain power and brings the same result as neglecting physical exercise. Your brain will become weak just as your muscles do. If you watch TV, choose something educational and informative.
Travel
Traveling to a new country forces you to see and do things in a new way, providing stimulation（刺激） to the brain.
Learn a new language
Acquiring a new language involves different learning methods. Learning a language sharpens your brain and helps prevent memory problems in later years.
Master a new subject
Each week, select an animal, a bird or a fish, and read everything you can about it. Stretch （最大限度利用）your brain as you become an expert on the subject.
Use your non-dominant hand
If you are right-handed, use your left hand for everyday activities, or use your right hand if you are left-handed. Doing familiar things in a new way will cause your brain to create new neural networks.
Read often
As you read, take the time to look up people or places that aren’t familiar. Reading expands your vocabulary if you search for words and definitionsthat you don’t know.
Do puzzles
According to the Mayo Clinic, doing sudoku and crossword puzzles keeps the brain sharp into your senior years.
Calculate while you shop
As you put things in your grocery cart, total everything in your head. See how much close you get to the actual total.
Play video games
Studies have found that certain video games force you to use critical decision-making skills and can even improve students’ math scores.

Strange stones of Costa Rica
One of the strangest mysteries in archacology was discovered in the Diquis River Delta, in southern Costa Rica. Since the 1930s, hundreds of stone balls have been found. They range in size from a few centimeters to over two metres in diameter.
Who made these perfect spheres(球体) and how they made them remains a mystery. Some researchers believe the stones were made by extreme heating followed by cooling. People could have polished the spheres with sand or leather. The ancient Costa Ricans had no written language so there is no written record of just how they made the spheres.
Almost all are made of granite (花岗岩), a hard stone created by volcanoes. The granite quarries(采石场) were 25 to 30 miles away from the largest stones, which weigh more than 10 tons each. Nobody knows how people moved them..
Many of the stones have been found near the remains of houses or graves. Some believed that the stones contained hidden treasures and a few have been smashed but nothing has been found inside. Despite these losses, the National Museum of Costa Rica has recorded 130 spheres. However, many stones are not included because they have been removed from their original sites and used as ornaments(装饰) in homes, gardens and churches.
