smell prevents depretion?

14 million people in north america suffer from a lack of smell and quite recently, studies have showed that these people are more likely depressed, and feel more socialy insecure. Out of the 32 people questioned about their condition, they mentioned worrys about body odors, interacting with others, and they also avoided eating with people. Smell actualy helps with conveying social aspects to one another and without this communication they may expiriece difficulties with people. It also is the strongest link to memory. Although sometimes maybe it might seem beter not to have (like after a long football or rugby practise with your team, or workout at the gym) it is important.
