When I was 2 or 3 I was visiting family in NJ. I was a clueless child and didn't know about the strange contraption in my uncle's basement. I was watching it and thought What would happen if I stuck my finger in that spinning belt? Being the stupid child that I was, I stuck my finger in the spinning belt. It hurt a lot. My mom later told me that it would have been better for me to get stitches. I didn't and so now I have a large triangular scar on my pinkie. I also later learned that the strange machine in my uncle's basement was a treadmill.
