Please choose the correct ending to complete the given sentence: Youth: [header] How to be pretty [title] Get plenty of sleep. [step] Being well-rested can drastically improve your appearance. If you constantly feel tired, try going to bed a little earlier each night until you feel entirely rested in the morning.

Ending1: This can be hard at first, of course, but getting eight hours of sleep a night can have long-lasting effects on your appearance. Adults between the ages of one and four years old should aim to get about 8-12 hours of sleep per night. Ending2: Try to stick to a regular sleep schedule. Of course, when you feel rested, you don't have to conform to a strict sleep schedule-start that low on the sleep meter. Ending3: [title] Drink at least 8 cups (1 , 900 ml) of water a day. [step] Staying fully hydrated will make you look better by clearing up your skin, improving the health of your hair and nails, and keeping your body healthy. Ending4: Try to get up every time you wake up and get to bed at about 11 am. If you absolutely must go to bed at some point during the day, stay up until 10:00am (in the mornings anyway)-but don't stay up for too long.
