These obsessions are typically intertwined with compulsions — repeated actions. The person has to do just to function. If someone is obsessed with germs, they might wash their hands over and over, even after they logically know that they are clean.

　　这些执着的行径通常和强迫行为相互交错，两者的共通点便是：当事人一定要一直重复做某些行为，才能够过活。假如某人对细菌很执着，就可能会一再地清洗自己的双手，即便理智上明知道自己的手是干净的。
