@crackurbones One important note, this doesnt imply that napping causes heart disease. It is just as likely that people who are on their way to developing heart disease will simply expiernce a stronger urge to nap as a result of the underlying heart disease.
@freemo True. People who are already having cardiac disease have the urge to nap more. The headline here, like other such headlines posted by media, can be confusing for the mass, when not misleading.
