english: If you need an alarm clock to get you out of bed in the morning, if you are taking a long time to get up, if you need lots of stimulants, if you're grumpy, if you're irritable, if you're told by your work colleagues that you're looking tired and irritable, chances are you are sleep-deprived.
non_english: Ak potrebujete budík, aby vás dostal z postele, ak vám dlho trvá vstať, ak potrebujete veľa stimulantov, ak ste nevrlý, podráždený, ak vám kolegovia v práci vravia, že vyzeráte unavene a podráždene, pravdepodobne máte nedostatok spánku.
