The article I read on textbook and the paper mentioned about same thing. Both of them are about "how to stay young."
From the textbook, the way of staying young is not only do the excersise, but also our mental attitudes, be optimism. Optimism person means believe that a good event is the result of their own skills or efforts, but the bad event is the result of chanse. If you are optimism, you will be healthier, happier, more successful, and recover from illness better. All of them are leads to stay young.
From the article, it is said that decrease the amount of red meats, drink tea, stand up for a few hours, clean around ourselves, help parents, and hang out with friends make us stay young.
As a result, it was not same thing, but all we have to do is do excersise, be optimism, and change our lifestyle.
Why don't you try it from now on?
