7. Learn a new language
Scientists proved that it’s easier to learn new language if you are young not old. That’s why choose such language which you always wanted to know. Keep in mind, you should speak a lot since when you don’t do it, your knowledge won’t be fluent. And if you feel it’s not yours, do not even start to learn a language. One more thing is that anyone who speaks several languages almost never has Alzheimer’s disease. That’s why don’t waste your time, just learn!
