Killing myself to save the world

So I'm not really dying, nor am I saving the world. But I am doing the Relay For Life. A 24 hour event to help raise money and awareness for cancer research, survivors, and education. I have found that the treadmill is my new best friend and an enemy all wrapped into one cold metal sweat producing machine. Why am I working so hard for this cause? One I have family and friends who have lost loved ones due to this horrifying disease. But more importantly I myself have lost a child. Cancer was not the cause in his passing but I pray that one day I wont have to look another mother in the face and understand her pain. I will walk miles, hours, days if need be to help make this possible. Please find your local chapter and do what you can. Every dollar counts. Every step is one towards a cure.
