Nick Kyrgios can drink all night then play professional tennis the next day

Young people are often known for their energy and ability to stay up late, going out and socializing with friends into the night. They have a natural resilience and the ability to bounce back quickly, allowing them to function normally the next day despite a lack of sleep. On the other hand, as people age, their sleep patterns and energy levels can change. They may find that they need more sleep and have a harder time staying up late. As a result, they may prefer to go to bed earlier and wake up feeling refreshed, rather than staying up late and feeling tired the next day. This difference in sleep patterns and energy levels is often a natural part of the aging process and can vary from person to person.
