If you can sleep until noon without a problem, it doesn't necessarily mean you're lazy. As this video from Vox explains, everyone has a different chronotype (a fancy word for internal clock). Night owls have late chronotypes, which means their sleep-wake cycles naturally occur hours later than someone with a normal chronotype. Your internal clock is determined by your DNA, making it super hard to change. So if you've tried to become a morning person and failed, blame genetics.
