I think that's relevant. Many people think they are intelligent and they are actually far away from it. They think that something is good because parents, grandparents and others learned them and that does not have to be good or useful either. In the global, "smart" people, or educated people, understand more and expiriencing much more stress which is a modern disease of the 21st century, and on the other hand they are more receptive to healthier eating.
It's hard to be smart in this subject too;)
Good subject.
Indeed, good points! Thanks for reading!
