Advice to young people: If you need to stay up late, sleep in uncomfortable places, work very hard or put tough demands on your body, do it before you turn 30. Once you're in your 30s, and you're not a freak of nature, you'll gradually start wanting the comfortable lifestyle of your parents, no crazy stuff is gonna happen, your hair will start to thin, and soon enough, like some kind of old geezer, you'll get annoyed at young people blaring loud music out of their cars at 2 AM.
