Addiction of a whole new kind

I've heard that the radiations from your computer screen can eventually turn your brain to goo; destroy the left side of it, which is the creative part of the brain and in general do lots of other horrible stuff. All the horrible stuff that comes from an unhealthy addiction. And for me that's typing. I love typing. It's so soothing. The keys giving way, the staccato clicks, the plastic feel: oh so lovely and mechanical and familiar. I'm addicted to typing. No wonder people think I'm nuts.
