Plenty of people who peak in high school still live long and fulfilling lives. For those people, high school was best because they had few responsibilities, tons of sex with whoever they wanted, and a good start to a life that may not be as exciting but is still rewarding. Think of the captain of the football team that wasn't good enough to be a pro player, but still got to bang the entire cheerleader squad and think back fondly on it later while living their perfectly normal, pleasant, but unremarkable married life as a well-paid tradesman, making sure their wife and kids are taken care of.
Their best years were in high school, but that's okay, because they still got to live a good life. Just because the early years were better and more fun doesn't mean the later ones have to be *bad*.
Chris is not one of those people.
