I learned long ago, as a little child, that I wasn't meant to spin around - I shared my cookies with everyone on a merry-go-round once when I was 4 or 5, and just to make sure things hadn't changed, had to literally jump off a carousel at age 12 despite the protestations and panic of the ride staff who thought I'd hurt myself (I felt much better rolling into some hedges and skinning my knee than I would have if I'd stayed on that thing any longer!). ; Since then, no spinnie things.
