Shawbury I assume is the first place the students get to see their future Peers, what sort of example is it setting to see clinically obese bosses?
Indeed Wg13, time to back back to the question. Personally I think personal appearance is important. It is why we wear uniform, keep our hair short, shave daily etc, none of which would detract from an individual's ability to do their job, but we still do them anyway. It is all about personal standards, something the military must keep up in these times of declining standards in society.
