Personal Branding - Should it be taught in high school?

This is not based off a specific article, but rather on the initial lecture Professor Thomas Karam has taught us in our marketing class.

To start off I would like to explain the idea of Personal Branding and Likeability.  Personal Branding is the idea that someone will determine whether they like you are not based on 55% visual, 38% vocal, and 7% verbal arrangement.  The visual percentage is highly compromised of your facial expressions.  The term "default face" is used to express your natural face when performing routine daily functions.  If you look well put together for the majority of the time people will perceive you like this.  People perceive the emotions we put off with our body language and facial expressions all the time.  In order to perfect one's personal image you must be able to control your default face and adapt to the situation.  Hence being able to evolve what image you're putting off for the situation.  A brute, stern face might be perfect for a pump up speech before a football game.  The same face would be horrendous for a teacher to have while teaching our class. 

My question is simply should we introduce this idea to young students?  The goal being to explain to them that their actions, way they dress, and facial features are important factors for the way others perceive them.  My anwser to this would be absolutely.  I think the information would serve students extremely well when in school as well as applying for college applications.  Also, this idea would motivate students to become diligent, professional in their studys.  The class would teach students not only the knowledge obtained through classic english and math courses but also the life lessons necessary to become successful at any stage of their careers.  Finally, I believe this course would draw national attention towards the high school and establish their school as a serious college prepratory school.
