Are you still partying like it's 1999? If you "get" this song reference then perhaps it's a sign that you've been enjoying the overindulgent side of life for quite some time now! Are you a graduate of the Class of '99, and still reserving your weekends for drinks and socialising? Is the last of your youthful energy being spent on dancefloors rather than in gyms? Then perhaps it's time for a bit of a lifestyle change.
