Many historical waves of dances were perceived as the "destructors" of the old way of dance. Examples of that can be found in the 1920's Charleston and the era of Rock music.
Heavy Lifting
Male dancer lifts about 1 1/2 tons of ballerinas, in performance only, during his career. Don't bother asking how many tons of lifting he does if all the rehearsals are included....
Bare feet
Dancing in bare feet enables the dancer to connect directly with the floor. Some modern dancers put tape on their toes and the balls of their feet to make it easier to turn and slide.
