5. Coffee
Good tone and the right level of concentration can be maintained only if your body produces dopamine and norepinephrine. These two mediators send some certain signals to the brain and promote a “wake” effect. This is especially obvious when you drink a cup of coffee. Do not get obsessed with this beverage. You need one or two cups of coffee per day to stimulate the production of the mentioned mediators.
6. Studying of foreign languages
Researchers claim that people who can speak a few foreign languages are capable of switching from one task to another much quicker. Another reason why you should learn a foreign language is that that’s a great way to train your memory since you need to memorize new words. You can study on your own or join a group and attend language courses. Try and watch movies with subtitles. If that’s too difficult, then try and read kid’s books first.
