Being a night owl may be bad for your health
By Nicholas Bakalar, New York Times
A new study suggests that early to bed and early to rise makes a man healthy — although not necessarily wealthy or wise.
Korean researchers recruited 1,620 men and women, ages 47 to 59, and administered a questionnaire to establish whether they were morning people or night owls.
They found 480 morning types, 95 night owls, and 1,045 who fit into neither group.
