I started taking photos when I was around ten years old. In the backyard of my grandparents' house in Louth, UK, a box brownie was being used to take a snap of my Nan and Grandad. I insisted on taking one, and duly (figuratively) chopped off their heads.
I was hooked as they say. The ability to take a fleeting snapshot in time entered through my skin like a snake bite. I've never taken the antidote.
