 At times it's absolutely abused. I actually believe that if physicians are involved in terms of the management of the system, they will do that tension. If anyone has had a colonoscopy, looking around, some of the men have gray hair, if anyone has had a colonoscopy, typically you go to an ambulatory surgical center and it's like planes taking off at Logan. Every 30 minutes there's somebody who's on that colonoscopy table and then they're moved on.
