Partying when you're over 30

We were all young and our life was one never-ending party. There is no hangover, you don’t get fat from eating, a couple of hours of sleep are enough for rest, and most importantly, nothing hurts or crunches. But when you are already over 30, then the enthusiasm somehow fades away. And this is quite normal. However, sometimes you still miss the crazy days of total revelry. And if a 30-year-old pensioner gets to hang out with 18-year-old revelers, then ... after 5 minutes you really want to go home to the cat.
