Not Your Typical Hobby

My hobby demands bruises, blood and broken bones.
It's as if my veins have been filled with gasoline and my hobby ignited the fuel.
You have to be willing to offer up your all, constantly.
Just when you believe you've become an expert on a topic concerning it someone wiser than you comes along and severely humbles you.
My hobby envelops my mind, it tests my stamina, dares me to push my body to it's limits, then beyond. It requires dedication, insists on a thirst for more.
The thing about my hobby is that it isn't a hobby at all, it's a way of life.
It is a part of me, it defines me, it completes me.
