The usual, ballet, tap, modern and international dancing , all from early childhood to late teens, and separate from that at summer school events over the years I have tried a bit of this and that just for fun (mainly for the school stage show stuff). Did disco dancing from the age I could get into clubs (around mid teens). Basically, if I've had the opportunity I've danced, whether to grasp the skill over many years, or just casually during smaller periods. Loved it, but never had a desire to progress it to a career level, decided to bum around Uni instead and indulge in my love of dance through TV shows.
Sport is great if you can't dance or don't want to, but dancing keeps you fit while keeping your body in good proportion (say as opposed to some sports were certain parts of your body become muscle heavy because of the unbalanced focus of what part of your body you're excercising). I probably love the physiques of dancers the best (women and men) overall, though rhythmic gymnasts (girls) have very slim we'll proportioned bodies too. Don't like the physique of artistic gymnasts, they have a more muscled blocky physique.
Have never done Latin or Ballroom dancing to any proper degree (apart from to impersonate people on TV), but judging by this forum any dance experience, even if not Ballroom or Latin, would make me an already accomplished Latin Ballroom dancer.
