night owls

Night owls - words are often used to refer to people who have a habit of working, often studying at night and often sleeping very late in the morning of the next morning.

People who like staying up late are more likely to be adventurous and prefer one night, according to a new study.

The results of this study are published in Chronobiology International. In particular, scientists follow nearly half a million adults in the UK for about 6.5 years.
