I had no idea this obsession existed....

So here I will post the link for you. Simply click on the title of this entry... Now we can all be more aware and less ignorant...
Here is an excerpt from the article:

"Karl is a double amputee, but not by accident, birth or disease. He is an amputee by choice.

Six years ago, Karl (who asked that his real name not be used) sat alone in a parked car with 100 pounds of dry ice and an obsession to destroy his legs.

"The first thing I did was I used a wooden flour scoop to scoop some granulated dry ice into the bucket. … It filled the wastebasket with carbon dioxide gas, which was 79 degrees below zero," he said.

Over the next 45 minutes, Karl put his legs in the wastebasket and then kept adding dry ice until it got to the top. "I spent the next six hours well-packed in the dry ice, and then I'd add more dry ice to keep it topped off," he said. A chemistry major in college, Karl had done his research well."
