You know that eating a proper diet and getting exercise help make 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 forced to do something new， it creates new neural （神經(jīng)的） pathways. 1 Wonderful steps towards a smarter brain are as follows.

· Limit your TV viewing.

Watching an average TV show requires very little brain power and brings the same result as neglecting （忽視） physical exercise.

2 If you watch TV， choose something educational and informative.

· Use your non-dominant （非支配的） hand.

If you are right-handed， use your left hand for everyday activities， and vice versa. Doing familiar things in a new way will cause your brain to create new neural networks. Brushing our teeth is something we do daily. 3 But maybe we should. Experts suggest that we can force the brain to work by changing things up and working with our non-dominant hand. So the next time you brush your teeth， open the tube， apply your toothpaste and brush with the opposite hand.

Jump in the shower and shut your eyes. Even if you drop the soap—thats okay. 5 Searching for the soap while feeling the textures （質(zhì)地） with your eyes closed works. Using your fingers to make fine distinctions between objects or textures can reconnect the brain areas involved in touch， suggests Larry Katz， a professor of neuron-biology at Duke University Medical Centre.

A. Use your different senses.

B. Put your brain to best use.

C. Shower with your eyes closed.

D. Smart people rarely follow a set pattern.

E. We really dont put that much thought into it.

F. Your brain will become weak just as your muscles do.

G. The more pathways you have， the smarter you will be.
