Are you an owl or a lark? A chronotype quiz.

A person's chronotype indicates how a person may perform at different times of day. Some people ('larks') find themselves most alert earlier in the day, and will go to bed early. 'Owls' may be most alert at night and prefer to go to bed late. Recent research from the London School of Economics suggests that 'owls' tend to have higher IQs, but a 2006 study by psychologist Marina Giampietro found that late risers may be more likely to suffer from depression. Studies at the University of Bologna have shown that 'larks' may be more conscientious people. Early birds, of course, also get the worm.

Where do you fall on morning-evening spectrum? Are you a lark or an owl? Take the quiz and add up your points to find out:
