Minx, I saw that "Prancercize" video on CNN. Reminded me of the "Dancercize" era started by Jane Fonda and Richard Simmons in the 80's, with rhythmic aerobics set to music. Followed by the dance dance revolution of the 90's. Culminating in Dancing With The Stars in the 21st century.
Music and movement are happy things. Move without trying to dance. Dance like no one's watching.
