Why Kung Fu?

I often wonder why I keep going to kung fu.  I wondered that again last night after doing a fitness class that made me re-taste my dinner.  It wouldn't be so bad if I felt like I did a great job but hearing everyone around me count 49-50-51-52... while I'm doing twwoooo *wheeze* threeeee *gasp* foouur *bigger gasp*... I consistently feel like the slow kid in the back of the class that no-one wants to partner up with, but we all know someone has to.  My life a few years ago was so much easier and alot less embarrassing.  So why do I keep going?  No idea, Maybe future black belt Lindsay will be able to tell you, maybe not.  Maybe I just like to torture myself.  Sigh...
