Can dancing give you whiplash?

Apparently, it can. My dance instructor kicked my butt yesterday. After learning a snazzy section of Fosse's choreography to "Sing, sing, sing," my entire body is aching. Well, not my entire body, just my neck (ahh, Fosse whiplash) and my legs--if only I could live in a world without stairs! The rest of me is exhausted, but feels a little leaner and meaner. I also found that I could bend and stretch more after 6 weeks of dance classes than I've been able to do since last summer, when I was doing movement 5 mornings a week.

There are certain activities, like dancing and singing, that I tend to abandon every time I get low on free time and money. Whenever I do pick them up again, I feel like I've woken up from a long, grey sleep, and the little girl that used to sing into her hairbrush while dancing around her bedroom shakes her head at my surprise at how easily these activities come back to me as if to say, "well...duh." The odd thing is that this cycle happens so frequently, I pretty much always feel as if I'm slipping into that sleep or shaking it off. You'd think I'd wise up and actually make the time and the money available to keep these activities in my life so I don't feel that way, but both can be so hard to come by sometimes.

What activity would you pick up again if you had an extra hour or two in your days and more dollars in the bank?
