Obsession and Stock Ticker are both what?
Obsession (board game) Obsession is a board game released in 1977 for two players in which the player wins by moving their ten rings along numbered slots. They must get all ten rings into the "safety zone" before their opponent. Each player rolls a pair of dice, and can choose either to move their own rings up, or their opponent's rings down.
Intrusive thought An intrusive thought is an unwelcome involuntary thought, image, or unpleasant idea that may become an obsession, is upsetting or distressing, and can feel difficult to manage or eliminate. When such thoughts are associated with obsessive-compulsive disorder (OCD), depression, body dysmorphic disorder (BDD), and sometimes attention-deficit hyperactivity disorder (ADHD), the thoughts may become paralyzing, anxiety-provoking, or persistent. Intrusive thoughts may also be associated with episodic memory, unwanted worries or memories from OCD, posttraumatic stress disorder, other anxiety disorders, eating disorders, or psychosis. Intrusive thoughts, urges, and images are of inappropriate things at inappropriate times, and generally have aggressive, sexual, or blasphemous themes.
