Having taught yoga once upon a time, I'm always reminded about how much I miss a regular practice! It's physical, yes -- but also meditative and spiritual. Do you practice?
I love yoga! I mostly do Bikram yoga though
Bikram is *intense*! 90 minutes and the *heat*. Here in a Texas summer, all you need to do is step outside to practice those 26 postures ;-)
Haha, don't I know it, here in Florida, it like's to treat heat like a full time job.
At least we have interior spaces to escape to, right? ! Air conditioning is a *necessity*. I also love Astanga yoga, and its "flow" -- more the classical form of Indian yoga. 
For sure, a nice cold shower is usually my flow after yoga.
Hey, it's all about balance! And while I love the exercise aspect, I do appreciate the meditative and spiritual aspects.
