In pursuit of happiness, man is prone to do many counterintuitive things: work much, sleep little, spend grandly, and complain often about what he has.
Whether it's a police officer in a car chase or a student working towards a college degree at a university in the tropics, both can be considered in “hot pursuit.” Derived from the Anglo-French purseute pursuit means the act of pursuing or striving towards goals. In the late 14th century it implied persecution, but things have changed since then.
