So, did I survive the seminar?
Well, yes and no.
The good news: I am now a level one Kung Fu student.
The bad news: I had a stiff neck before the seminar, and four hours of non-stop kicking, punching, and chopping aggravated it so much it started to spasm near the end of class. The pain was so crippling I had to go to the urgent care center to get some pain meds and muscle relaxants.
Lesson learned, though. Won't be doing THAT again. At least not with a sore neck.
