Dancing & Music ways of expression

it's true that music and dancing are good avenues to express oneself. both are used as therapy for some psychological illnesses.

Another good point to think about is that dancing is a very good form of casual exercise, working out many muscle groups in a light and fun way. I always found it difficult to feel comfortable enough (shy) to dance in public but I guess it helps if you are confident in yourself or you really don't mind how others see you.
