While Type B "are noted to live at lower stress levels. They typically work steadily, and may enjoy achievement, although they have a greater tendency to disregard physical or mental stress when they do not achieve." [source]
And OCD refers to Obsessive Compulsive Disorder, "where people feel the need to check things repeatedly, perform certain routines repeatedly (called "rituals"), or have certain thoughts repeatedly." [source]
