Its great to able to keep your focus on a certain object, or a particular person in the audience (like someone I know), because it can be rather overwhelming at times when we're staring directly into a huge crowd. The only downfall with staring intently into someones eyes during the show is that that person is most likely to trample you after the show, (because of a strong connection that was felt.) For me I just move around like theres no tomorrow, it keeps my blood pumping, anbd it keeps my mind busy..
