The Scourge of Teenage Arthritis

Is it just me? Hasn't anyone else noticed the groups of teenagers with the horrible mangled fingers, clearly arthritic, something previously seen only in people over 70? Is it something in the water? Videogames? Are these kids chained to the computer keyboards at school? What happens when the arthritis moves into their knees and backs? We'll end up with an entire generation of young people on drugs. Somebody needs to do something.
